Silicone Technology HRS OVERVIEW OF THE SILICONE RUBBER

Silicone rubber’s special features such as “Organosiloxanes Polymer” has been originated from its unique molecular structure that they carry both inorganic and organic properties unlike other organic rubbers. In other words, due to the Si-O bond of Silicone Rubber and its inorganic properties, Silicone Rubber is superior to ordinary organic rubbers in terms of heat resistance, chemical stability, electrical insulating, abrasion resistance, weatherability and ozone resistance etc...

With these unique characteristics, Silicone Rubber has been widely used to replace petrochemical products in various industries like aerospace, munitions industry, automobile, construction, electric and electronics, medical and food processing industry. Recently, these scopes of silicone application have been expanding at a great speed by the demand of industries that want more reliable elastomer.

Main Characteristics of Silicone Rubber: - Excellent High and Low Temperature Resistance. - Excellent Electrical Properties. - Physiological Inertness. - Excellent Weatherability. - Oil Resistance. - Flame Retardant.

GENERAL PROPERTIES

1. High bonding energy

Silicone rubber has siloxane bond (Si-O) of molecular structure as the main chains. While carbon bond, C-C, carries 84.9 Kcal/mol, siloxane bond carries 106.0 Kcal/mol It shows that siloxane bond has greater capacity and stability. As a result, silicone rubber has better heat resistance, electric conductivity and chemical stability than any other ordinary organic rubbers. Siloxane bond’s energetic stability is secured due to sharp difference between Si and O in terms of electro-negativity making Si-O to be closest to ionic bond.

Bonding Energy Kcal/mol (KJ/mol) Classification CSI C 84.9 (349) 58-80 (240-340) Si 58-80 (240-340) 45 (189) H 98.8 (414) 72.6 (304) O 83.2 (349) 106.0 (423)

2. Low intermolecular force with spiral structure

With its coil shaped spiral structure and low intermolecular force, silicone (dimethylpolysiloxane) is highly elastic and compressible. Furthermore as methyl groups are located in the outside of coil structure, they are free to rotate on its own. As a result silicone rubber has outstanding water repellency and contact resistance.

04 _ 05 HTVHIGH TEMPERATURE VULCANIZATION Silicone Rubber is classified into HTV (High Temperature Vulcanization) and RTV (Room Temperature Vulcanization) by its curing temperature. Also, HTV is divided into Millable Type Silicone Rubber and Liquid Type Silicone Rubber by its degree of polymerization.

Millable Type Silicone Rubber. HRS Silicone / HTV

Millable Type Silicone Rubber is composed mainly of Polyorgarnosilioxan(Silicone Polymer) and Silica with various additives to grant diversified characteristics. We call this stage for Silicone Rubber as “Base Compound”. Then this “Base Compound” is catalyzed, pigmented with roll and cured by press molding and extrusion etc...

Due to its status, Millable Type Silicone Rubber is also being called as “HCR (High Consistency Silicone HIGHRubber)” in the market. TEMPER Properties of Silicone Rubbers

Heat Resistance Electric Properties Heat resistance of silicone rubber is Silicone rubber is being used for the one of its most excellent properties insulation materials at high and provides the basis for its creation. temperature with its superior insulation Silicone rubber is far better than properties. It is particularly known for organic rubbers in terms of heat wide range in temperature and volume resistance. At 150 , almost no alterations of properties take place resistance between 1014 cm and 1016 cm. Silicone rubber that it may be used semi permanently. Furthermore, silicone rubber experiences lowest change in performance in wet condition and is withstands use for over 10,000 consecutive hours even at 200 the best fit for being used as insulation materials. By adding special and, if used for a shorter term, it may also be used at 300 as conductive fillers, conductive silicone may also be manufactured. In well. Boasting this excellent heat resistance, silicone rubbers are particular, silicone rubber is strongly resistant against corona widely used to manufacture rubber components and parts used in discharge compares to others, while being widely used for high-temperature places. insulation purposes in high voltage environments.

Cold Resistance Electric Conductivity Cold resistance of silicone rubber is Conductive silicone rubber is a the finest among organic rubbers. It compound comprising conductive provides a critical reason behind the materials such as carbon black, silver creation of silicone rubbers. Natural and copper. Depending on the type of and ordinary rubbers demonstrate silicone rubber, they range in resistance significant changes in formation depending on temperatures. They level from a few cm to 103 cm. One of the properties is that its become soft at high temperatures and hard at low temperatures so electric properties are not much affected by variance in that they may not be able to used any more. While other organic temperatures. No rubber materials are not found yet to match the rubbers may only be used up to -20 or -30 , silicone rubber electric properties of silicone rubber over 200 . Conductive maintains its elasticity between -55 and -70 . Some of the silicone rubber is also being used for keyboard interfaces, antistatic products even withstand temperatures as extremely low as under - parts, and shield materials for high voltage cables. 100 .

Radiation Resistance Weatherability Compares to other organic rubbers, Silicone rubber has superb ozone ordinary (dimethyl) silicone rubber has resistance. Due to corona-discharged no special performance in terms of anti ozone, other organic rubbers become radiation. However, methyl phenyl soften at a higher speed, but silicone silicone rubber adopting phenyl group rubber is rarely affected. Furthermore, in polymer molecules does have radiation resistance to be used for even long-term exposures to UV rays, winds, or rain silicone cables at nuclear power plants and connectors. rubber's physical properties will not be changed substantially.

Silicone Technology HRS RATURE VULCANIZATION

Steam Resistance Oil Resistance Silicone rubber absorbs only 1% of Silicone rubber is inferior to ordinary moisture even after experiencing long organic rubber in oil resistance at exposure to water without being room temperature. However, for affected in mechanical strength or automobiles or aircrafts that require electric properties. Generally, silicone high temperature resistance, it rubber does not deteriorate even after having contact with steam demonstrates higher performance. Even when in contact with under atmospheric pressure. In high pressure steam over 150°…, automobile oil, silicone rubber does not inflate significantly by siloxane polymer is cut off and rubber properties decline. Such a reason of swelling. It swells in non polar organic compounds such property may be improved by the composition of silicone rubber, as benzene, toluene, and gasoline. But its materials do not selection of curing agent, and the post curing. Other modified disintegrate or dissolve unlike ordinary organic rubbers. If solvent is products are also available with improved steam and boiling water removed, it would be restored to the original conditions. resistance.

Non toxic Flame Retardancy Silicone rubber is physiologically inert, Silicone rubber does not easily burn and is thus used for baby nipple and when in contact with a flame, but stoppers in medical application. would burn out consistently once Silicone rubber is also very ideal ignited. However, by adding a small elastomer for making swimming caps amount of flame retardant, it may and goggles. become flame retardant and self-extinguisher. Flame retardant silicone rubbers presently in use would scarcely produce toxic gas during combustion since they do not contain organic halogen compounds discovered in organic polymers.

08 _ 09 LSILIQUID SILICONE INJECTION MOLDING LSR is Liquid Type and High Temperature Vulcanization Silicone Rubber. LSR differs from Millable Type Silicone Rubber and RTV (Room Temperature Vulcanization) by its degree of viscosity and curing temperature.

HRS Silicone / LSI LSR is perfect rubber material for automated injection molding due to its excellent liquidity. Also, LSR is ideal for complex molds, demanding design and tolerance because it can be easily filled almost every complex part of a mold.

LSR also does not generate volatiles or residue during the curing process and it makes LSR possible to be used that required inertness for example pacifier, diving mask, medical tube, snorkel and bakeware. LIQUID SILICO Applications of liquid silicone Caution 1. In order for curing not to happen before LSI enter the mold, the LSI is a material suitable for numerous uses from automobiles, temperature of the nozzle and cylinder should be lowered to spaceships, high-voltage insulators to sculptures, baby products, etc. about 20 . Copying machine roller / High-voltage insulators / Keypads / Anode 2. Demolding what is cured at an extremely high temperature caps / Connector seals / Diaphram & valves / O-ring, Gaskets & Seal / (above 200 ) can produce volatile materials. It is recommended Diving mask & snorkels / Baby nipple / Wire seal / Gromet to use a system which will remove them. Supply capacity and container size Post cure Both A and B are supplied. The inside diameter is as follows. Most of silicone rubbers are to have the best properties after 20KG : 282mm ( Can ) 200KG : 572mm ( Drum ) curing. Compression set, however, can increase in case of post- curing at 200 . What are manufactured for injection molders in general can be used. At this temperature, a fire can break out due to an emission of the Storage volatile siloxane. Thus, fresh air should be supplied into the post- curing oven for secondary hardening (100 liter of air per 1kg of LSI should be stored in a cool and dark place with good ventilation silicone rubber) and no direct sunlight. Please do not forget to close the lid after using it. With the lid closed and in the normal temperature range, it can be Linear shrinkage used with stability for 6 months (in case A and B are not mixed). Make Linear shrinkage differs depending on the thickness. As the sure to close the lid after use. Also the drum is recommended to be thickness decreases, linear shrinkage increases, and vice versa. It used as soon as possible after opening. also differs depending on the curing temperature. At a higher Pot life temperature, linear shrinkage usually increases. Linear shrinkage is a factor which must be considered in designing If the mixture is inside of a cold mixer and injection molder at the the mold. mixture ratio of 1:1, it can be used for up to 3 days. The new one Take LSI-200/50. At 171 and with the thickness of 2mm, its should be supplied from the 4th day. linear shrinkage is as following.
