Question 1: What makes kitchenware-grade silicone rubber different from ordinary food-contact silicone?

Answer: One sentence: kitchenware grades are platinum-cured LSRs engineered to pass food-safety limits without the costly second bake — VOC held ≤0.4% straight off the press.

Standard peroxide or addition compounds must be oven-post-cured (typically 200 °C × 4 h) to burn off volatiles before food contact; MY LSR 3750 series is designed for exactly that burden to disappear, conforming to BfR, FDA, and RoHS requirements as-molded. Selection rule: spatulas, bakeware, baby items, seal rings at injection-molding volumes → no-post-cure kitchenware grade; gaskets and non-contact parts → general food-grade lines suffice.

Question 2: What specs and processing facts decide a good kitchenware silicone grade? Can other food-grade LSRLs substitute?

Answer: Let's look scenario by scenario (based on measured parameters of commercially available grades):



Conclusion: Kitchenware grade earns its name through as-molded compliance, not a softer recipe — the whole value is skipping the post-bake while still clearing BfR/FDA migration expectations. Other food-grade LSRLs can substitute only if your factory already runs validation-governed post-curing ovens; conversely, a kitchenware grade used for non-food parts wastes nothing but cost margin. Practical guidance: ① demand batch-level migration test reports (overall and specific-substance limits for fatty simulants), not just a compliance slogan; ② confirm your pigment and additive package is also food-approved — a compliant base polymer doesn't launder a non-compliant color paste; ③ tune demold/handle temperature to the actual part thickness since fast surface cure can trap volatiles inside thick sections. Validate taste/odor panel, compression set in hot oil use, and dishwasher-cycle aging on production samples before launch.
