liquid silicone rubber to make formwork panel mold made in china 

General DESCRIPTION

E630#  concrete molds silicone is generally named two-components silicone rubber, Part A and part B.  is very suitable for making silicone rubber stone molds.

*It is featured with extremely low shrinkage, good fluidity and resistance to many kinds of chemicals; 

*This material do not release any  by-productwith low molecular weight during its curing process, 

and it's cured from top to bottom and from the inside and outside  simultaneously, namely, deep curing. 

*The silicone will not have the problem of degradation,  sticky mold surface caused by the existence of by-product of small molecules under certain conditions, (such as closed environment, high temperature).

of small molecules under certain conditions, (such as closed environment, high temperature). 

*Known from our customer's feedback,  it is very convenient  to make cement molds, and it is a high quality silicone for construction industries. Further more, it can be applied to make multiple piece mold for products with  complex design.

APPLICATIONS of concrete molds silicone

E630# concrete molds silicone can be used in the field of construction applications. Because the vulcanizing

reactions of addition cure silicone is fundamentally different from tin cure silicone's, it has some characteristics that the 

condensation cure type do not have, such as adjustable curing rate, being completely environmentally friendly, and so on . 

Therefore, our platinum cure silicone is particularly applicable for large stones molds, artificial stone molds, 

plaster and other architecture elements replication.  

FEATURES of

-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 temperature and aging(resist -60 to 200°C)
-excellent non-stick effect
-food grade silicone (environmental,odorless and nontoxic)

Datasheet of concrete molds silicone

Why does the silicone mold have few molding times?

The silicone rubber mold has few molding times is due to following reasons: adding too much silicone oil which will destroy the molecular of silicone material; making the mold for small and fine detailed products with higher hardness silicone material which is easy to break; making the mold for large products with soft silicone material which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
