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
