The shape T polyamide thermal barrier material can prevent the window frame from dust and water, also has a more firmness mechanical performance than the shape I, mostly used on the sash.
For the shape T, we can provide the following size or customize according to customers’ requirements.
The strips will be stored in the ventilated and dry environment, horizontally placed, paying attention to waterproof, keeping away from the heat source, avoiding heavy pressure and the contact with acid, alkali as well as organic solvent.
For all specifications/shapes, they could be packaged in linear, the length will be 6 meters, or customized.
For the Shape "I", "C", and some simple shapes, they can be packed in rolls 400-600 meters/roll.
