PVC Adhesive Coated Car Window Weather Stripping With Enhance Tensile Strength

PVC Adhesive Coated Car Window Weather Stripping With Enhance Tensile Strength Special Advantages

1. Our new PVC aluminum alloy spine weather stripping for cars can provide good protection for automobile windows or other parts of car. The aluminum strip has a good sealing ability, thus this strip can help the car window to be closed sealed.

2. PVC has high resistance of the external environment. It has high heating resistance and can even prevent fire.

3. Aluminum is thin and light. Today car industry focuses more on reducing weight of the whole car, thus aluminum which is a light material will be more beneficial to car producers.


PVC Materials

PVC material is one of the most usual used industrial materials in the world. It has good tensile strength and yield strength, thus it is suitable to be the materials for structural items. PVC materials thus can also brings aluminum strips better protection of the car windows or other car parts.


Two-coat Paint Systems

The two-coat paint system generally refers to a primer and a topcoat on the same side of the strip. The pretreatment also know as “conversion coat”, is not consisdered a coating and is applied in addition to the primer and topcoat. Therefore, a two coat system generally consists of the pretreatment, a primer and the topcoat.


Primers are formulated to offer superior adhesion between the aluminum substrate and the topcoat which can be called a bonding agent to bond a vast range of elastomers to metals and plastics during the moulding process.

The slitting line of PVC aluminum alloy spine weather stripping for cars

Designed for slitting of narrow and thin coils in soft conditions, ensures:

No sticky winding and no staining;

Less manipulation after slitting, less risk for damage and contamination;

Uniform tension throughout the whole coil via most accurate control systems;

Consistent slit edge quality due to accurate tooling: very low burr and edge deformation results in stable behaviour during the process.


Chemical degrease line of PVC aluminum alloy spine weather stripping for cars

Our material for multi-layer pipes has a special chemical degreased surface for excellent adhesion between aluminium and polyethylene

It is proven by peeling tests on different types of pipes that the adhesion with chemically degreased aluminium is much better than with only thermally degreased aluminium.



Packing details:

l Normally, for aluminium strip, 20MT can be loaded into 20 foot container,we suggest to use 20 foot container, the sea freight rate is much cheaper than 40 foot container.

l The packing is very strong, which has 3 lays, thick fiber, foam, plastic,enough drying agent, suitable for long distance sea transportation.

lWe use wooden pallet and steel pallet according to customer request;

l Wooden boxes will be used in the outside packing.

l We have fixing in the container to avoid any damage during the transportation.
