Product Description
Product Description of Liquid Silicone Rubber for shoe sole mold making

RTV Silicone Rubber is a kind of two-component material, and the silicone rubber is consisted of Part A silicone rubber base and Part B CA30 curing agent, and the silicone rubber base and curing agent can cure at room temperature by a condensation reaction. These materials can be cast into the cured silicone rubber mold: shoe mold making, sand casting etc.

Applications of Liquid Silicone Rubber for shoe sole mold making  

Liquid Silicone Rubber can be applied in many objects mold making, since silicone rubber has good flow ability and medium hardness, and the silicone rubber can cure at room temperature, thus it's a good material for duplication.
Liquid Silicone Rubber can be used for artificial stone mold making. For example MCSIL-2066 and MCSIL-2088 silicone.
Liquid Silicone Rubber can be applied in candle and soap mold making, such as MCSIL-215 and MCSIL-218 silicone.
Liquid Silicone Rubber can be used for plaster mold making, such as MCSIL-2025, MCSIL-H25 and MCSIL-2030 silicone.
Liquid Silicone Rubber can be applied in the field of shoe sole moldmaking, for example, MCSIL-S10 and MCSIL-S15 silicone.
Liquid Silicone Rubber can be used for prototyping and electronic potting.
Liquid Silicone Rubber Material for Shoe Moldmaking is suited for shoe mold, simple products, sand casting mold making, and shoe mold by pouring way.
Storage&Shelf life of Liquid Silicone Rubber for shoe sole mold making

When the Silicone Rubber material for Shoe Moldmaking is stored at or below 30 °C (85°F) in the original unopened containers, RTV3010/3015 silicone rubber base and CA30 curing agent have a usable life of 12 months from the date of production.


Why does the liquid silicone rubber for molding have few mold making times?
The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products
