silicone rubber for tyre segment mold
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 Rubberis has been used for years to make tire pattern molds .
Characteristics
*low shrinkage (less than 0.1% )
*high tensile and tear strength with high copy times
*easy for operation (mixing ratio at 1:1 /10:1)
*very good flow and easy for pouring operation
*Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat
