Food-grade silicone

【Product Overview】

A two-component food-grade liquid silicone composed of Component A (silicone base) and Component B (platinum catalyst) precisely mixed at a 1:1 ratio. This product is FDA-certified for food contact and suitable for manufacturing food-contact grade molds.

【Core Features】

1. Ultra-low shrinkage rate: <0.01%, ensuring precise product dimensions

2. Deep curing capability: No thickness limitation, achieving uniform curing for depths over 30cm

3. High-temperature resistance: Continuous resistance at 300°C, peak resistance at 500°C

4. Food safety: Complies with food contact material standards

5. Mechanical properties: High tensile strength, tear resistance

6. Process adaptability: Supports room temperature/heated curing

【Process Parameters】

Mixing ratio: A:B=1:1 (by weight)

Pot life: 30 minutes at 28°C environment

Curing time:

- Room temperature curing: 2-3 hours (full vulcanization)

- Thermal curing (60-120°C): 10-40 minutes (depending on mold volume)

【Operating Specifications】

1. Pre-treatment:

- Use dedicated mixing equipment (recommended with vacuum degassing device)

- Mold surface requires release agent pre-treatment (platinum system-specific release agent recommended)

2. Mixing process:

① Precisely weigh Components A and B (error ≤ ±1%)

② Low-speed mixing until homogeneous state

③ Vacuum degassing (-0.095MPa, maintain for 5 minutes)

3. Precautions:

❗ Strictly avoid contact with sulfur, phosphorus, and nitrogen compounds (may cause curing inhibition)

❗ Operating environment humidity must be <60% RH (avoid surface tackiness)

❗ Dedicated tools required (prohibit mixing with condensation silicone tools)

【Quality Assurance System】

1. Storage conditions:
