Description

It is an A/B A two- component, semitransparent silicone rubber. Take platinum rhodium complex as sulfurizing reagent. The material is perfect to the process of squeeze products

 

Application

High rebound silicone tube as well as mechanical silicone tube/bar.

 

Advantages

Simple operation

No additional vulcanizing reagent needed

Fast vulcanizing, high efficiency

Odorless and tasteless

Stable dimension

Good transparency

Smooth surface

Excellent anti-yellowing

 

Usage 

1. Mix ratio：component A: component B＝1000 parts:1000parts

2. Clean mixing mill. Mix rubber until smooth edge and surface of the rubber formed by double roller mill.

3. Extrusion process---Discharge the mixed rubber from mixing mill , cut it to appropriate dimension, then do extrusion process

4. Suggested curing condition: 400℃--600℃ by vertical oven

5. The press molding condition can be adjusted according to the dimension of product
