1. Applications of Mold making silicone rubber:

 

Moulds for the small producation of parts in various materials(plaster, wax, reconstituted stone.various resins(epoxy,acrylic. polyester), silicone elastomer)such as :

A Decorative items :comices , columns.,omaments. statues.

B Figurines:toys,candles, giftware,soap,craft projects,sculpture.

C Furnishing :castingof furnitrue and decoration

D Construcation :prefabrication of decorative features,pavement,paveing stone,urban furniture concrete casting.

 

 

 2. Advantages of Mold making silicone rubber :

 

A. Shore A from 10to 30 hardness liquid mold  rubbers.

B. Good fluidity and good operability and good for pouriing method .

C. Excellent mechanical properties.in particular tear strength and tensile strength.

D. Excellent flexibility and it is easy to demould.

E. High temperature resistance,high duplication times and repeated use.

F. Range of catalysts allows the M 20 to fulfill requirement for various,

 4. The differences of M20, M 25, M 30

 

A. M 20 is mainly used for mold with small,delicated patterns.Pouring  method is the best way because of good fluidity .The hardness is 20 shore A.

 

B. M 25 is for medium size mold making .It's also used for pouring methods.The hardness is 25 shore A.

 

C. M 30 is applicable for large mold making since hard hardness.Both pouring and brushing method are ok.The hardness is 30 shore A.
