Product Description

Silicone rubber for tires molds making Description :

Silcone rubber for tires molds making are generally named as two-part silicone rubber that vulcanises at room temperature.Part A is a flowable liquid, part B is the curing agent. It features an exceptional fluidity ,good operability,excellent physical properties and very low shrinkage. The mixing ratio between Part A and Part B can be 100:5 .

Silicone rubber for tires molds making application:

Rapid prototyping (urethane casting/silicone tooling/vacuum casting)
Concrete moulding
PU resin casting
General Mouldmaking
Superior manual mold designs
Cake/Chocolate molds

Silicone rubber for tires molds amking Main properties:

almost nil shrinkage
high chemical resistance to aggressive components of some types of resins
good tear strength (this feature ensures higher resistance to wearing and shearing)
high degree of precision in reproduction
high dimensional stability over time and non-deformability
high resistance to high temperatures and ageing (resit to -60-200°C)
excellent non-stick effect
environmental, odorless and nontoxic
