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.

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.
