FAQQ1:Are you trading company or manufacturer ?
We are a manufacturer, We have our own workshop producing electrical insulation polyimide film..
Q2: Can you send samples for testing?
A4size Samples are free supplied, customers just need to pay a litter shipping charge.
Q3: How can you guarantee the quality of mass goods is same as the sample sent to me before?
We kept another same sample and marked on company when we sent to customer. So our production
will be based on and also we will test the product before shipment.
Q4: Which package do you use?
Package is important part to avoid goods breaking in transportation. We will choose suitable packing depend on materials.
Package&Storage:
Packed in rolls and in carton; store at room temperature; avoid fire. The storage period is 12 months.
