Ruihe® - Liquid Silicone Rubber for Food Grade Mold
                         
 Additives include stabilizers, masticating aids and colorants.    

To become an elastomeric material, raw silicone rubber has always to be cured. This can be done either by peroxide or addition curing. Peroxide curing involves the use of organic peroxides.      

Features:

This product boasts a range of excellent properties, including high transparency, high strength, good resilience, and minimal deformation. It is also highly resistant to yellowing and aging, ensuring long-lasting performance.
Furthermore, this product meets rigorous safety and quality standards, including compliance with US FDA CFR 21.Part.177.2600 and European EN14350-2 Section 4.9 Volatile Compound Test Standards, as well as European ROHS and REACH Standards.
When mixed and sealed, the A/B components have a safe operation time of 3 days at 20°C. However, it's important to note that higher temperatures can shorten the safe operation time.

               
 
Properties Data

This series of products is two-component addition liquid silicone rubber, it has excellent performance of resistance to high temperature , good weathering resistance, outstanding transparency, high tear strength, good rebound ability , and good anti-yellow properties.
 
 
Additive
Compared with other elastomers, silicone rubber requires few additives because the essential properties are determined by the siloxane polymer used. Thus, a finished polymer compound may consist only of polymer and filler.
 
​Particularly notable is the fact that silicone rubber is free of curing accelerators or retarders, organic plasticizers and organic antioxidants.
