Temperature

℃	NBR	HNBR	FKM	EPDM	VMQ	PU (AU)
Min. T	-25	-25	-15	-40	-45	-35
Max. T	100 (120)	110 (130)	200 (220)	130 (150)	200 (220)	80 (100)

Note: the use of temperature range is affected by sealing medias, use conditions, required performance and other factors.

* Max. T: This value accounts the results of air heating degradation testing. The number shown in ( ) is the heat-resistant

temperature under temporary use, should be avoided for a long period of continuous use.
* Min. T: Suit for TR10. TR is Temperature-Retraction, indicating the recovery of deformation in low temperature. TR10 value refers to the pre-given temperature when deformation recovery 10%, is the standard value of low temperature service limit.

FAQ

Q1: What is the payment term?
A: Normally, T/T 30% deposit and 70% balance of a current bill of lading or a letter of credit.
Q2: What is the normal delivery time?
A: The average delivery time of the sample is 1-2 weeks. If the mold production is involved, the delivery cycle of the production mold is 15 days, and the average production time after the sample is approved is 2 weeks.
Q3: What is your standard packaging?
A: All goods will be packed in PE bags and then packed in cartons on pallets. Individual pack or special packaging methods are accepted when needed, but charges may apply.
Q4: How do you control the quality of bulk orders?
A: Our inspection procedures include, material testing/process inspection/initial inspection/full inspection/shipping inspection. We are ISO 9001, IATF 16949 Certified. PPAP is available.
Q5: How do I choose a raw compound for my application?
A: With years of experience in using a variety of materials, we can help you choose the material that best suits your needs, keeping in mind the cost of materials.
