What You Can Source

Food-Contact Silicone Material Options

You can compare the main food-grade silicone routes in one place: solid HCR for molded parts, platinum-cured HCR for selected clean applications, LSR for injection molding, and low-migration grades for specific kitchenware requirements.

Peroxide-Cured HCR

For transparent solid silicone parts requiring food-contact compliance, molded stability, and multiple hardness choices.

TY171 reference series Shore A 33–72 in table FDA / LFGB / olive-oil migration pass

Platinum-Cured HCR

For molded parts that need platinum curing, transparent appearance, food-contact support, and controlled processing.

TY5151 reference series Shore A 43–81 in table Tear 25–40 N/mm

Food-Grade LSR

For injection molded parts where transparency, color customization, flow, and curing speed are important.

TYL-6120 / TYL-6421 Shore A 30–71 in table Good flow and fast curing

Low-Migration HCR

For selected large and flat kitchenware projects where lower olive-oil migration and post-bake stability are more important than transparent appearance.

TY171-H reference series 220℃ × 8h post-bake support Yellowing risk after post-cure

Reference Performance Ranges

This table focuses on confirmed material parameters from supplier data. Final material confirmation should still consider geometry, pigment, curing route, post-curing, processing condition, and finished-part testing.

Manufacturing Capability

Manufacturing Routes for Food-Grade Silicone Materials

Your food-grade silicone material can be matched with different production routes according to part structure, hardness, tolerance, surface finish, volume, and compliance requirements.

HCR Compression Molding

For solid silicone parts using peroxide-cured or platinum-cured HCR, with hardness, demolding, flash, and post-curing reviewed together.

LSR Injection Molding

For transparent, colored, or precision food-contact LSR parts requiring stable flow, efficient curing, and repeatable molding control.

Transfer Molding

For selected structures where material flow, insert positioning, part detail, or cavity filling requires a transfer molding route.

Extrusion

For silicone tubes, strips, profiles, sleeves, and continuous food-contact parts requiring stable section control.

Food-grade silicone finishing and post-processing

Finishing & Post-Processing

For trimming, deflashing, post-curing review, color control, inspection, packaging, and other project-specific finishing needs.

Food-grade silicone material and mold evaluation

Material & Mold Evaluation

Material choice is reviewed with mold structure, gate design, parting line, wall thickness, tolerance, and demolding risk before sampling.

FAQ

Food-Grade Silicone Material Questions

Key questions your team may need to confirm before food-contact HCR or LSR material selection.

Can you recommend HCR or LSR for our product?

Yes. Product geometry, hardness, surface requirement, volume, tolerance, color, assembly needs, and compliance documents should be reviewed before HCR compression molding or LSR injection molding is selected.

Can the material support FDA and LFGB projects?

The reference food-grade HCR and LSR material tables include FDA, LFGB, and olive-oil migration pass records. For a specific project, final test scope, market requirement, pigment, and finished-part testing plan should still be confirmed.

Do you provide low-migration silicone for kitchenware?

Yes. Low-migration HCR options can be reviewed for selected large and flat kitchenware. The reference data mentions lower olive-oil migration and 220℃ × 8h secondary baking support, but this route is not preferred when transparent appearance is required after post-curing.

Can hardness and color be customized?

Yes. The reference material families cover multiple Shore A levels. Color can be customized, but colorant, transparency, post-curing, and compliance requirements should be reviewed together before mass production.

What should be sent for a quotation?

Please send drawings or sample photos, dimensions, target hardness, product use, food-contact market, color requirement, expected quantity, packaging needs, and any required testing standard or customer document format.
