Epdm Seal Strip Good Low Temperature Performance

EPDM seal the advantages and disadvantages

advantage:

1, low temperature performance, can reach -60 ℃ and maintain flexibility;

2, high temperature, continuous working temperature up to 110 ℃ or more;

3, chemical resistance, can resist brake fluid, water, coolant, detergent, alkali and other chemical media;

4, excellent aging resistance, ozone resistance, weather resistance, up to 10 years of service life.

Disadvantages

1, the price is slightly expensive;

2, welding difficult;

3, single color, usually black;

5, poor adhesion;

6, rubber seal after vulcanization process odor, and can not be recycled can not be degraded, the pressure on the environment.

Recommended places to use:

EPDM seal of various excellent performance, but the price is high, a single color. Suggests its application: For the mechanical properties, heat resistance demanding, less demanding on the appearance of the site, such as: doors and windows on the outdoor side of the need for frequent switching of dynamic sealing occasions.

TPV seal material is a blend of EPDM and PP, the use of dynamic vulcanization technology will be a mixture of two substances made of a stable elastomer. Mainly used for automotive doors and windows seal, door and window seal in the past few years began to be used.

TPV seal strip Advantages:

1, high temperature: 100 degrees deformation, low temperature, -40 degrees do not harden;

2, compression deformation is small, can ensure that the sealing effect is good;

3, good weather resistance, long-term use;

4, oil, smell small, can be VOC testing, matte, delicate, feel good anti-static performance, do not stick to dust;

5, simple equipment, easy processing, high production efficiency, low production costs;

6, a small proportion (only 0.9-0.95); looks high purchase price, the actual use of low cost;

7, recyclable, non-halogen and lead and other heavy metals, plus a few years after recycling, in line with the requirements of green building materials;

8, the performance and service life of vulcanized EPDM rubber seal;

9, processing energy relative to vulcanized EPDM strip low (with PVC equivalent).

TPV seal strip Disadvantages:

Moderate compression will permanently deform

Recommended places to use:

Compared with the EPDM seal, the price of the TPV seal is relatively low, with little difference in performance. Suggests its application: In most cases, it is applied to the static sealing parts of doors and windows and the places where the compression set is not too high.
