Features:
- It features high transparency, high strength, excellent resilience, low deformation, resistance to yellowing, and aging resistance.
- Complies with U.S. FDA CFR 21 Part 177.2600, European EN 14350‑2 Section 4.9 for volatile compound testing, as well as the European RoHS and REACH regulations.
- At 20°C, the pot life of the A/B components in a sealed state is 5 days; this pot life decreases as the temperature rises.
Applications:
- Suitable for manufacturing food-grade products such as baby pacifiers, baby bottles, bottle caps, infant tableware, and a range of baby toys.

Note:
- Vulcanization conditions: After thoroughly mixing components A and B in equal parts, mold the material in a 140 mm × 120 mm × 2 mm die at 175°C for 5 minutes.
- This data is for reference purposes only and should not be used as a basis for specifying the performance of specific products.
Packaging Specifications
- Suitable for 200 kg/drum and 20 kg/drum.
Precautions
- Store at room temperature in a dry, well-ventilated indoor location, away from direct sunlight. Shelf life: 12 months.
- During storage and use, contact with compounds containing nitrogen, phosphorus, sulfur, tin, or lead can poison the platinum catalyst, thereby impairing the sulfidation process.
