FAQ


Taking “Qinghui” to the world

Location: Home> FAQ
Do you supply materials or finished parts?
We supply modified materials — modified PVC, TPE, TPR and TPV pellets — for extrusion, injection molding and other processing. The parts shown under Applications are validation samples made with our own materials, not products for sale.
What material series do you offer?
Modified PVC (soft extrusion and injection grades, high and low temperature, low-VOC, glossy, matte, rigid), TPE, TPR, and TPV (wear-resistant, high-temperature, high-flow). They cover interior and exterior trim, window and sunroof seals, roof and windshield seals, water scrapers, insert and bright strips, bumpers and edge guards.
Which material suits my part?
Match it to the service condition. Long-term outdoor sealing and trim parts — water scrapers, window and sunroof seals — usually call for TPV or TPE. Interior parts with low odor or low VOC need low-VOC PVC. A glossy or matte finish calls for glossy or matte PVC. Send us the part, the process and the key performance targets, and we will recommend the grade.
What performance do your materials reach?
Many grades meet imported US and Japanese standards, and we also develop high-temperature, low-temperature and wear-resistant grades. Hardness (Shore A), temperature range, compression set and UV or aging resistance vary by grade — ask us for the data. Give us your service environment and our engineers will match the right grade.
How do you handle environmental compliance?
We offer a low-VOC PVC series for automotive interiors, and our materials meet RoHS and REACH. If you have OEM or industry emission and odor standards, tell us in advance and we will test to them.
Can you develop a custom formulation?
Yes. Send your target properties — hardness, tensile strength, temperature and weathering ratings, odor, haze — and we will match the material and recommend a grade. We also support you through processing and equipment setup.
What is the sampling process?
1) You specify the part, process and key requirements; 2) we recommend a grade; 3) we run small-batch trials and ship samples; 4) we adjust the formula after your feedback. Lead time and sample quantity depend on the grade.
What is the MOQ and lead time?
Both depend on grade and order volume; standard extrusion and injection grades are usually in stock. Contact us for an exact figure.
Which reports can you provide?
We test the material itself, not finished parts, and issue reports on mechanical, thermal and weathering properties. Third-party or OEM-specified reports can be arranged on request. See Testing Equipment for our lab.
How is batch consistency assured?
We work with a materials research institute under a strict production-academic-research system and follow through from trial to mass production, so quality stays consistent batch to batch.
What are your supply and logistics advantages?
We are in Dagan Industrial City, Ningbo Economic and Technological Development Zone, next to Beilun Port. Raw materials and finished goods turn over efficiently, which keeps your supply schedule on track.
