Product Description

 

6250-70YH High Rebound High Hardness Shore A 70 Liquid Silicon Rubber To Make Mold Factory

 

 

Description

 

RUI-HE 6250-70YH is a kind of two-component liquid silicone rubber for injection molding processes, consisting of part A and part B. Liquid Silicone Rubber possesses natural transparency, this attribute makes it possible to produce, colorful, custom, molded products. All LSR are platinum cured (vulcanized) materials which are mixed in a 1: 1 ratio by weight.

 

 

Key Features and Benefits

 

Liquid silicone rubber molding has several advantages, including:

  • High transparency
  • Easy pigmentable with the LSR Color Pastes
  • A wide range of high/low-temperature extremes
  • Good resistance to yellow
  • Rapid vulcanization
  • Superior compatibility with human tissue and body fluids
  • High rebound property
  • Sensational weather resistance
  • High stability to ozone and ultraviolet light

Knowledge

 

Operation ways of Injection Molding:

 

1. Mixed: Part A (based glue) and Part B (curing agent) ratio of 10:1 or 1:1 by weight, mixed, mixed either manually or using the equipment.

 

2. Vacuuming: mixed silicone A and B, When used in small amounts can be in a vacuum desiccator under vacuum, the volume will foamed plastic material can be increased 4-5 times, so degassing vessel volume should be less than bulky plastic material 4 to 5 times, after a few minutes gel volume returns to normal, no air bubbles escaping when the surface (about 10 minutes) to complete the degassing step.

 

3. Clean your Original mold (sex toys molds), pls note that, the molds won’t contact with condensation silicone rubber before, and not contains a chemical element such as N.S.P, otherwise the silicone won’t be cured.

 

4. Pour the silicone rubber into your sex toys molds.

 

5. cured the silicone rubber at 80℃ to 120℃, then the silicone will be cured, and then de-mold.
