PU Foam Door Seal Good Aging Resistance, Durable
Oct 20, 2017

The PU Foam Door Seal can be divided into two categories: static PU Foam Door Seal between relative static joint and moving PU Foam Door Seal between relative motion joint. Static PU Foam Door Seals are mainly a little PU Foam Door Sealed, rubber PU Foam Door Seals and contact PU Foam Door Seals of the three major categories. According to working pressure, static PU Foam Door Seal can be divided into middle and low pressure static PU Foam Door Seal and high pressure static PU Foam Door Seal. Medium and low pressure static PU Foam Door Seal common material is softer, gaskets wider gasket PU Foam Door Seal, high pressure static PU Foam Door Seal with material is hard, contact width is very narrow metal gasket. Dynamic PU Foam Door Seals can be divided into rotary PU Foam Door Seals and reciprocating PU Foam Door Seals of the two basic types. The contact PU Foam Door Sealing and non-contact PU Foam Door Sealing can be divided into the contact type of the parts according to the relative motion of the PU Foam Door Seals. Generally speaking, the PU Foam Door Seal of contact PU Foam Door Seal is good, but it is limited by friction and wear, suitable for the occasion with low PU Foam Door Sealing surface speed. Non-contact PU Foam Door Sealing PU Foam Door Seal is poor, suitable for high speed occasions.

PU Foam Door Sealing material should meet the requirements of PU Foam Door Sealing function. Because the PU Foam Door Sealed medium is different, and the working condition of the equipment is different, the PU Foam Door Sealing material is required to have different adaptability. The requirements for PU Foam Door Sealing materials are generally:

1 Material compactness is good, not easy to divulge the medium;

2) have appropriate mechanical strength and hardness;

3 The compressibility and resilience are good, the permanent deformation is small;

4 No softening at high temperature, no decomposition, no hardening at low temperature, no brittle crack;

5 corrosion resistance, in acid, alkali, oil and other media can be long-term work, its volume and hard {Hottag} degree change small, and do not adhere to the metal surface;

6 friction coefficient is small, wear resistance is good;

7) has the softness which unifies with the PU Foam Door Seal surface;

8 anti-aging good, durable;

9 Processing and manufacturing convenience, cheap, easy to draw.
