Guide to the Use of Car Window Rubber Seal Strip

Car window rubber seal strip is one of the important parts of automobile, which is mainly used to seal the gap between window and car body, prevent external factors such as water, wind and dust from entering the car, and improve the sound insulation effect in the car. Using high-quality rubber material, the þéttilist úr gúmmíi for car window has excellent weather resistance, high and low temperature resistance, ultraviolet resistance and flexibility, and can meet the use requirements in different environments. The design of sealing strip should not only consider its sealing performance, but also ensure its durability and elastic recovery ability in long-term use, and ensure the comfort and safety of the car.

Function of Car Window Rubber Seal Strip

Waterproof seal: the car window rubber seal strip can prevent rainwater and car wash water from entering the car and keep the car dry.

Sound insulation and noise reduction: the car window rubber seal strip can reduce the transmission of external noise into the car and improve driving comfort, such as isolating tire noise and wind noise on the road.

Dust-proof: the car window rubber seal strip prevents dust, pollen, etc. from entering the car and keeps the car clean.

Shock absorption: the car window rubber seal strip absorbs the impact force when the window is closed, reduces the vibration and protects the window glass and related components.

Keep warm and save energy: to some extent, reduce the heat loss in the car, help to keep the temperature in the car and reduce the energy consumption of air conditioning.

Material of Car Window Rubber Seal Strip  

Ethylene propylene diene monomer (EPDM): Excellent comprehensive performance, outstanding ozone resistance, good weather resistance, adaptability to a wide temperature range (-40℃~+120℃), chemical corrosion resistance, and not easy to age and crack. It is currently the commonly used material of car window rubber seal strips.

Silicone rubber: It has good high-temperature and low-temperature resistance, can still maintain good elasticity and sealing performance at extreme temperatures, and has high chemical stability, but the cost is relatively high.

Neoprene: It has good weather resistance, oil resistance and wear resistance, but its cold resistance is relatively poor.

NBR: The oil resistance and wear resistance are good, but the weather resistance is not as good as that of EPDM, so it is relatively seldom used in automobile window þéttilist úr gúmmíis.

Polyurethane rubber: It has the advantages of high strength, high elasticity and wear resistance, but its price is relatively high. This kind of car window rubber seal strips may be used in some high-end cars or models with extremely high sealing performance.

Common Problems and Causes of Car Window Rubber Seal Strip

Aging and hardening: the rubber seal strip for car windows is exposed to the sun for a long time, and the chemical components in the rubber are gradually decomposed, resulting in hardening, cracking and even breaking of the sealing strip.

Softening deformation: in high temperature environment, the þéttilist úr gúmmíi of window is easy to soften and lose its elasticity and sealing performance; Being in a high temperature environment for a long time or being affected by contact with high temperature objects.

External force damage: Foreign objects are entrained when the window rises and falls, or hard objects are used to scrape the surface of the sealing strip when cleaning the window, resulting in physical damage to the car window rubber seal strip.

Chemical corrosion: Cars are often parked in the open air, and the surface of the rubber seal strip for car windows comes into contact with chemical substances such as acid rain, car wash liquid and oil stain, which corrodes the rubber.

Improper installation: When replacing the car window rubber seal strip, if it is not completely attached to the edge of the window during installation, or improper force is applied, the sealing effect will be affected, and even the sealing strip will be deformed and damaged.

Maintenance and Maintenance Methods of Car Window Rubber Seal Strip  

Regular inspection: the owner should regularly check the state of the car window rubber seal strip, especially when changing seasons, to see if the surface is cracked, hardened, peeled off or damaged.

Cleaning and maintenance: when cleaning the car, try to avoid using cleaning agents containing strong acid or alkali, and choose neutral car wash liquid; After cleaning, use a special rubber protector and apply it to the car window rubber seal strip regularly to enhance its anti-aging performance.

Avoid exposure to the sun: Try to choose a cool position when parking to avoid prolonged exposure to the sun; When conditions permit, the car cover can be used to reduce the ultraviolet exposure of the car window rubber seal strip.
