Features of Additional cure liquid silicone rubber for mold making
1.environmental, food -grade(It is environmental protection
material and our addition cure silicone rubber can be used for food
3.resistant to UV-irradiation, aging resistance
5.good flexibility, permeability
Different hardness of silicone rubber suitable for different types
We can provide liquid additional cure silicone rubber with
1. For small size and dttailed pattern(within 30cm), 15-20 shore A
can be applied, which is easy for de-molding and will not damage
2.For the products with medium size, such as 50cm, 25-30 shore A
silicone rubber should be used.
3.For products with large size, such as 1m, 35-40 shore A shall be
recommend to avoid deformation.
4.If the product is large but features detailed pattern, 30 shore A
silicone rubber will be workable.(It will be better to protect the
products from deformation to make outer mold.)
Note: All the above products hardness should be adjusted according
to customers' requirements.
Operation instructions of Additional cure liquid silicone rubber
for mold making:
1. Stir part A and part B with right mixing ratio (1:1 or 10:1)
evenly. And get the mixture for vacuum-pumping. (If there is no
vacuumizer, you can just pour the mixture slowly from the corner so
