Basic Models:
LSR1966-34A/B, LSR1966-39AE/BE

Product Description:
SQUARE^® LSR1966-34A/B and LSR1966-39AE/BE are 2-part addition-type liquid silicone rubber catalyzed by platinum. Mixing ratio of two parts is A:B=10:1. With medium viscosity, the 2-part LSR is suitable for pour molding processes.

Product Features:
1. Good elasticity, ease of demolding
2. Great thermal stability and freezing resistance (Usage temperature: -50℃~230℃)
3. Stable shrinkage rate
4. Catalyzed by platinum, non-toxic and free from odor
5. Excellent physical property, high rollover frequency

Main Applications:
The liquid silicone rubber is ideal for molding of thermosetting resin such as epoxy resin, as well as for molding products for art works and ornaments.

Packaging:
Available in 2kg/pot or 20kg/pail
