Advantages:

FDA compliant grades,suitable for medical, food and cosmetics industry;

Transparent but easy to color, odorless, tasteless

Superior elongation, 100~900%, extremely low compression set and superior resilience

Wide temperature range, -50 to 180 degree at pure state, -90 to 250 degree by adding stabilizer

Wide hardness range, 10~90 Shore A

Excellent resistance to chemical, oil, oxidation, light, UV and X-rays

Easy two-shot over-molding onto thermoplastic and metal parts, even with complex designs and geometries

Applications:

Liquid Injection Molding System (LIMS) is a rather new method of Silicone processing. The liquid Silicone components A B are metered, loaded and cured precisely and automatically. Liquid injection is ideal for electronic, automotive, medical, healthcare, baby nipple/pacifier, food, kitchen ware, diving mask and many other applications.
