Car industry seals often have problems with excessive hardness and poor collision prevention and sealing effects. These problems may be related to usage time and the quality and workmanship of the seal. Remember to gently press the seal with your finger when purchasing car door and window seals to test its resilience, thickness, and deformation. Door and window seals must be moderately soft and hard, with uniform thickness and good resilience and resistance to deformation. Use your finger to check the seal at the seal groove; does it wobble when pulled? If the seal wobbles significantly, pull it out completely and reinstall or replace it.

Car door anti-collision, dust-proof, and sound insulation seals require high-quality rubber that is resistant to aging, does not easily deform under prolonged compression, and has a good sealing and sound insulation effect. If breakage or detachment occurs, replace it as needed; severe issues may cause door deformation or detachment. Trunk seals are available in adhesive and groove types; overall, they ensure dust prevention for the trunk.

The trunk seal plays an absolute role in dust prevention and sound insulation. Trunk seals are prone to cracking, which is caused by seal quality, untimely dust cleaning of the car, or prolonged sun exposure. Pay attention to the dust and placement of your car, and avoid prolonged sun exposure and regularly clean the interior and exterior dust.

There are various ways to classify automotive sealing products. They are usually classified according to the name of the installed part (component), material type, number of composite materials, and working characteristics. Classification according to the name of the installed part (component) is the most common method. This includes engine compartment seals, front and rear windshield seals, door frame seals, door seals, door glass guide groove seals, lower door dust strips, inner and outer door window sill seals, side window seals, sunroof seals, roof seals, and trunk (luggage compartment) seals.

Mainly used on car door panels, door frames, side windows, front and rear windshields, engine hoods, and trunk lids, they provide waterproofing, dust prevention, sound insulation, heat insulation, shock absorption, and decoration. Rubber hinges for installing coach luggage compartment doors can also be produced. The unique formula design gives the EPDM rubber seal superior aging resistance, high and low temperature resistance, and chemical resistance. It has good elasticity and resistance to compression deformation, and will not crack or deform after long-term use, maintaining its high sealing performance between -50°C and 120°C.
