/ Product description
Door frame rubber strip are used to seal gaps at door perimeters. By sealing the gaps along the door frame you can significantly cut down on the infiltration of sound, light, moisture, fire and smoke.
The Characteristic of PVC
1.The raw material granule is mixed by PVC resin- oatmeal and P83 nitrile rubber and plastic ,so its shock resistance and elongation at break than PVC,the cost performance is very good.
2.Physical performance:55-85A,temperature range is from -30°C to 90°C.
