Product Description
Food grade Injection Molding Liquid Silicone Rubber for Baby Nipple,Diving Glasses
1.This series product is the two-component, rapid molding liquid silicone rubber.
2.It is of sound property of high and low temperature resistance, weather-proof, good transparency and strong resistance of tearing strength as well as sound rebound resilience and yellowing resistance.
3.The series of products are high temperature curing speed, and liquid injection molding process.
4. It can widely used in food and medical products. For example, baby nipple, molar tooth plate, medical laryngeal mask, trident pipe, the kitchen with a cake pan, silicone shove and diving equipment etc.

1.Suggestions should be that users can use liquid injected molding machine to inject it to the mould and make the product.
2. A, B component should be fully mixed up in the weight and volume proportion of 1:1. Curing time is base on the mould temperature. If the temperature is high then the time will be short and if the molded product is thick and big, the time will be long. The mould can be taken apart after curing.
3. If the machine is stop operating (above two days), A or B rubber should be independently injected into the mix section or the static mixer of the injected molding machine be withdrawed and put in to the place with low temperature (< 1°C) and sealed, or wash away the remaining rubber.
