2014 new silicone liquid rubber molds for gypsum cornice molding 

Features of  molds for gypsum cornice molding  

silicone liquid rubber molds for gypsum cornice molding flowing liquid with general hardness of 22-50A° after curing with features:

1. Resistance to deformation and high-temperature, acid-alkali and expansion

2. Good tensile strength, tear strength and elongation

3. High reproduction times

Applications of silicone liquid rubber molds for gypsum cornice molding  

Mould making silicon rubber is suitable for industries such as toys, gifts, decoration, plate engrave, human replica, art crafts, 

resin crafts, poly resin crafts, unsaturated resin crafts, candle crafts, plastic crafts, stationeries, plaster crafts and Buddhist 

statue crafts

Package and storage of liquid silicone rubber for GRC molds making  

1. 20kg or 200kg /drum.

2. It is a kind of non-dangerous goods, and it should be stored at a cool and dry place, please keep it from sun and rain. 

Why could the silicone mold be reused only for a few times?

It can be due to the following reasons: 

a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which destroies the molecular weight of 

silicone rubber and reduce the tension and tear strength.

b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate 

designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs. 

(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this 

problem.)

and casting supplies serve as the raw material for casting molds, which can form cured silicone elastomer characterized by the resistance to chemicals, deformation, extreme temperature, acid & alkali and expansion. RTV-2 silicone rubber is mainly applicable for model making molds, resin mold(unsaturated, poly), sculpture mold, plaster & gypsum mold, architectural decoration mold, prototyping and molds for candle, art crafts, stationery, tyre, GRC product, plastic product, shoe soles, etc.
