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.
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
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.
Available in 2kg/pot or 20kg/pail
