High-Temperature Silicone Rubber H5350 - 50 ® Transparent Liquid
Silicone Rubber With REACH
Description
Rui-He LSR H5350-50 ® is a kind of two-component liquid silicone
rubber for injection molding processes, consisted of part A and
part B. It can be used to produce diving supplies with high thermal
stability and excellent resistance to acid and alkali. All LSR are
platinum cured (vulcanized) materials which are mixed in a 1: 1
ratio by weight.
Liquid Silicone Rubber Feature:
1. Fast-forming speed
2. Good Processability
3. Super-stable Physical Performance
4. Low deformation rate after compression
5. Good resilience
6. Injection molding
7. It complies with the related specification of ROHS, has passed
the detection of FDA and LFGB.

FAQ
1. What’s silicone products you are making?
--liquid silicone, silicone rubber, silicone oil; Due to different
silicone molds, our silicone has a different viscosity, and cause
different hardness, density to meet the requests from the client.
2. Do you offer a free sample to the client?
--Yes, we can provide the sample for the test.
3. How about the quality control in your factory?
--We have professional QC team to control the quality during
production. Goods will be 100% inspected before shipment.
4. How to remove the bubbles during my mold making?
--After mixing liquid silicone with a curing agent, please put the
material into vacuum machine to take off the bubbles.
5. How to get good silicone mold to use longer time?
--The best way is:
1, Please choose the right liquid silicone according to your
products.
2, Don’t use any silicone oil in mold making, because it can make
the silicone mold become too soft to use.
3, Silicone mold can be used longer after the whole silicone mold
fully cured, so it’s better to wait 2 hours after mold finished.
6. Why silicone rubber add curing agent after mixing a lot of
bubbles?
--This is normal physical phenomena. The liquid will produce a
large number of bubbles in the mixing time, so, it must pass
through the vacuum exhaust bubble treatment.
7. What is the temperature range of silicone products?
--Broadly speaking, the service temperature range of silicone is
within the region of -110C to +315C.
8. Does the outside environment affect silicone?
--No. Silicone is not affected by extremes of weather – hot, cold,
dry, wet, or humid. It also has excellent resistance to UV and
ozone degradation.
