Epdm Seal Strip The Advantages And Disadvantages

Edit:Rizhao Tongrui Rubber Products Co.,Ltd  Date:Sep 06, 2017

Advantages of EPDM sealing strip:

1, low temperature performance is good, can reach 60 ℃ and flexibility;

2, high temperature resistant, continuous working temperature can reach 110 ℃ or more;

3. Resistant to chemical media, such as brake fluid, water, coolant, detergent, strong alkali and other chemical media;

4. Excellent resistance to aging, ozone resistance and weatherability, which can last up to 10 years.

Shortcomings of EPDM sealing strip

1. The price is slightly higher;

2. Welding difficulties;

3. Single color, usually black;

5. Poor adhesion;

6. The rubber sealing strip has a peculiar smell after vulcanization process, and cannot be recycled without degradation. It is very stressful for the environment.

Recommended places:

EPDM seals have excellent performance, but high price and single color. It is recommended that the application situation: the mechanical property, the high heat resistance performance requirements are higher, and the place where the exterior requirement is not high, such as: the door and window facing the outdoor side need frequently the dynamic sealing situation of the switch action.

TPV seal material is a kind of stability elastic body which is mixed with PP and the two substances are mixed by dynamic vulcanization technology. Mainly used for car door and window seals, and in recent years, it has been used in building doors and Windows seals.

Advantages of TPV seal strip material:

1. High temperature resistance: 100 degree not deformation, low temperature resistance, -40 degree invariable hardness;

2. The compression deformation is small, which can ensure the sealing effect is good;

3. Good weather, long term use;

4. Oil resistance, small smell, VOC detection, sublight, fine, good anti-static properties, no dust;

5. Simple equipment, easy processing, high production efficiency and low production cost;

6. Small proportion (0.90-0.95); It seems that the unit price is high and the actual cost is low.

7. Recyclable, free from heavy metals such as halogen and lead, and can be recycled after several years to meet the requirements of green building materials;

8. Performance and service life are equivalent to the rubber seal of tri-propylene vulcanization;

9. The processing energy consumption is relatively low compared to the ethylene propylene rubber strip (equivalent to PVC).

Defects of TPV seal material:

Intermediate level compression can be permanent

Recommended places:

Compared with EPDM seal, the price of TPV seal is relatively low and the performance is not very different. It is recommended for application: most cases are applied to the static sealing parts of the doors and Windows and the situations where the compression permanent deformation is not too high.
