How to choose an impact modifier
Start with resin, target impact temperature, transparency/weatherability requirement, processing conditions and the application-test evidence available for each candidate grade.
Buying Guide
Practical answers for selecting, sampling, pricing and shipping polymer additives from China.
MBS vs acrylic impact modifier
Do not select only by product family name. PVC transparency, outdoor weatherability, impact target and processing behavior determine which family should be evaluated.
How samples work
For Engineering MBS RC-701/721/732/736/756/768, the confirmed commercial condition is a 5 kg free sample; customer pays sample freight. Other families remain unconfirmed until entered in the backend.
MOQ and lead time
For the confirmed Engineering MBS family, MOQ is 1 MT and lead time is 7–10 days after order before shipment/loading. Do not automatically apply these terms to HRP or PVC additives.
FOB and CIF
FOB uses the current product price. CIF needs current ocean freight allocated to the shipment plus explicit insurance. Missing or stale inputs should trigger an exact-quote request, not an invented number.
Comparable grades
An RC grade listed against an international grade means comparable for evaluation under the referenced evidence. It does not mean chemically identical or guaranteed drop-in replacement.
