What Is On File, And What It Covers

The silicone compound we mould is supported by eleven third-party SGS test reports, all Pass. Between them they cover restricted substances, environmental compliance and food-contact suitability. The table below is the actual evidence, with the report number for each test so you can ask us for the document that matters to your project.

Every report above was issued to the compound manufacturer for the raw silicone rubber supplied to us (sample "Silicone Rubber", grades TN750 and TN950). They are compound reports, not reports on a finished moulded part.

Restricted Substances and Environmental Compliance

For a buyer who has to evidence environmental compliance in an audit, this is the set of documents that answers the question - and it is the reason we lead material discussions with compliance rather than with a price.

Food-Contact Suitability

These are the standards behind food-contact silicone. If your product touches food, drinking water or skin, tell us at enquiry stage and we will match the grade to the requirement and send the reports that apply.

The One Caveat You Should Hold Us To

The reports cover the compound. Compliance of a finished part depends on the grade, the colour or pigment, and the process it goes through. We will not tell you that a part "is certified" - we will tell you which compound grade is supported by which report, and match the grade to your requirement at quotation stage. If a colour or a secondary process changes the picture, we say so before you commit.

What This Page Deliberately Does Not Claim

How To Use This In Your Project

Send us the requirement - the environment, the contact media, and any standard your customer or your market requires - and we will return the compound grade and the report numbers that cover it, as part of the quotation rather than as a separate request.
