Materials used in custom silicone molds

Silicone Rubber Mold

Silicone rubber is an organosiloxanes polymer. This special feature originates from its unique molecular structure in that it carries both organic and inorganic rubbers. It’s Si-O bond and its inorganic properties make it have more superior qualities compared to ordinary rubber. It exhibits heat resistance, resistance to abrasion, chemical stability, ozone resistance, electrical insulating and weather-ability.

HTV Silicone Rubber

Silicone rubber is classified into two groups based on the curing temperature. It is classified into High Temperature Vulcanization Silicone Rubber (HTV) and Room Temperature Vulcanization Silicone Rubber (RTV). HTV is further divided into two groups based on the degree of polymerization. It is divided into a Mill-able Type and Liquid Type Silicone Rubber.

Liquid Silicone Rubber

Liquid Silicone Type Silicone Rubber (LSR) has a different viscosity and curing temperature apart from the Mill-able type and RTV. LSR is well suited for injection molding owing to its excellent liquidity. It’s also very ideal for complex molds since it easily fits in the most complex parts of any mold

RTV Silicone Rubber

RTV silicone is made up of two components mixed in a ratio of 1:1. It exhibits many characteristics including work-ability, heat resistance, flow-ability, non-exothermic, dimensional stability and ease of mold release. It’s used for fire stop material owing to its fire retardant characteristics.

Silicone Sheet

Silicone Sheet exhibits thermal conductivity, very high-temperature resistance and is flame retardant. It is therefore very suitable for use in the thermal management of electronics and heat dissipation. Electronic products are growing smaller and thinner and are becoming richer in features making thermal management essential hence the growing demand for silicone sheet. Its demand is also getting wider into the automotive, medical and shipbuilding industries.
