FAQ

Switching to Chinese Materials, Safely

Can Chinese engineering plastics really replace imported grades?

In many applications, yes — we spent 20 years selling imported materials (Momentive, Evonik) into China and watched domestic grades replace them application by application. But substitution is never automatic: it depends on your exact grade, process window, and end-use requirements. That is why every replacement we propose goes through validation first.

How do you validate a Chinese alternative before we commit?

We start from your current grade's TDS and application requirements, shortlist candidate Chinese grades, then verify with sample testing — key mechanical, thermal, and processing properties, plus third-party lab reports where required. You approve pilot-lot results before any volume commitment.

Which imported brands can you cross-reference?

Engineering plastics from the major Western and Japanese suppliers, and silicone rubber lines such as Momentive TSE, Wacker ELASTOSIL, and Dow Silastic. If you send us a grade designation or TDS, we map it against qualified Chinese equivalents and flag where no true equivalent exists.

How long does substitution validation usually take?

A grade cross-reference with TDS comparison typically takes one to two weeks. Sample testing and pilot validation add four to eight weeks depending on test scope and shipping. We report progress at each stage so your team can plan the switch without supply risk.
