Product Description

6250-60KD A/B two part Liquid Silicone Rubber high adhesion industrial seals part Antistatic





Rui-He 6250-60KD A/B® 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 electronics keys supplies with a high rebound and good resistance to yellow. All LSR are platinum cured (vulcanized) materials which are mixed in a 1: 1 ratio by weight.



Key Features and Benefits


· High transparency

· High tear and tensile strength

· Good rebound property

· Excellent thermal and cold stability (-50 °C ~ 230 °C)

· Low yellowing

· Outstanding resistance to aging

Performance Testing


RUIHE Silicone has an extensive quality control system that tests the quality of raw materials first. Material cannot be used unless they are tested and meet our quality control standards. If it does not pass our incoming quality control testing, the material is refused and trucked back to the manufacturer.

Second, during the producing process, our quality control group will test the new batch of compound silicone rubber by taking some samples (twice from solid silicone rubber or three times from liquid silicone rubber) from different steps in process. After passing the test, this batch can be sealed to pack and deliver to the customers.



Packaging & Storage


Available in 20kg pails or 200kg drums.

Store in a cool, dry place out of direct sunlight, use it within 12 months from the day of manufacture.





This product cannot be contacted with compounds containing N, P, S to avoid affecting the catalytic effect of platinum.
