Liquid Silicone Rubber (LSR) | Mix Ratio 1:1 | 15-65 Shore A

Look for Durable LSR Silicone,Excellent resistance temperature, ideal for producing kitchen items (like spoons, spatulas, cup covers, ice molds), face plates.

And it’s also used for pacifiers, bottles, caps, infant tableware, pump seals, and baby toys.

Appearance of Liquid Silicone Rubber (LSR)
Part A: A non-toxic, odorless liquid with a translucent color, containing platinum.
Part B: A non-toxic, odorless liquid with a translucent color.

Note: Custom curing times are available upon request to suit your specific requirements.

Features of Liquid Silicone Rubber (LSR)

1) Exceptional fluidity, making it easy to work with.
2) Platinum-based formula—environmentally friendly, odorless, and non-toxic.
3) Available in a variety of delicate designs.
4) Flexible mixing ratios: 1:1 and 10:1 options available.
5) Easy de-molding for efficient production.
6) Outstanding tensile and tear strength for durability.
7) Superior performance in duplication and molding.
8) No shrinkage during curing or after hardening.
9) Excellent resistance to weathering, temperature extremes, aging, and acids. High resistance to both high temperatures (up to 250°C) and aging (-60°C to 250°C).

Caution – Safety First
1. Keep away from food, drinking water, and other consumables.
2. Ensure it is kept out of reach of children.
3. Since addition cure silicone uses a platinum cure system, improper handling can lead to uncured material. To avoid this:
– Do not mix with condensation cure silicone or tools used for condensation cure.
– Avoid contact with organic substances containing Nitrogen (N), Sulfur (S), Phosphorus (P), or ionic compounds like Tin (Sn), Arsenic (As), Mercury (Hg), and Phosphorus (Ph).
– Do not introduce pigments or powders without testing to ensure curing is not affected.
