Detailed Product Description
2-part liquid silicone rubber,catalyzed by platinum,suitable for injection molding processes.
1) Basic model: LSR39XXMU
2) Product Description
SQUARE@LSR39XXMU is one kind of 2-part liquid silicone rubber,catalyzed by platinum, mixing ratio of parts A:B=1:1,suitable for injection molding processes,meet biology activityrequirement of ISO 10993.
3) Key Features
High transparence
High tensile and tear strength
Good rebound property
High elongation
Excellent thermal and cold stability( -60°C~250°C)
Low yellowing
Outstanding resistance to ageing
Meet ISO10993 biological reactivity test,GB/T 16886.10-2000 and GB/T16886.5-2003 standard
4) Applications
Be suitable for making medical instruments used inside or outside of human body
5) Storage:
Stored in its original unopened container at room temperature (max. 30°C). it
has a shelf life of 12 months from the date of manufacturing.
6) How to use:
Ready-to-use mixtures(component A and B)are fed directly to injection molding machine from the original containers by means of a metering end mixing unit (called static mixer). The mixture(at the mixing ratio 1:1) is injected into the heated mould at the mould temperature of 160-200°C,the mixed silicone rubber will be vulcanized in a few seconds.
