Silicone Rubber For Tyre Molding

We are offering silicone rubber for tyre molding.
Description
hy- e series addition molding silicone is generally named two-components silicone
rubber, part a and part b. It features an exceptional fluidity and good operability.
The mixing ratio is 1:1 (10:1),mainly be suitable for making molds application.
Typical applications
hy- e series addition molding silicone could be mainly used for making concrete
stones, wax molds, pu molds, resin molds, gypsum casting, candle molding and
chocolate , candy and any other fda food product mold making,prototyping etc.
Hy-e620 silicone rubber is has been used for years to make tire pattern molds .
Characteristics
� low shrinkage (less than 0.1% )
