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.
