1.Materials:NR,NBR,EPDM,CR etc.

2.ISO 9001

3.Effective sealing performance

4.OEM,welcome your drawing

Tips:

The rubber material of the Packer rubber tube decided

the packer sealing performance is good or bad. Because of

the glue tube is nonlinear elastic material, the rubber formula

has a considerable influence on material properties.

The physical properties of the rubber material test

Main test items include:

(1) determination of tensile strength

   According to different samples, the WDL - 2500N tensile testing machine,

XK - 160 open rubber mixing machine, QLB - 25T flat vulcanizing machine

auxiliary complete the determination of tensile strength.

The test method should correspond the GB/T528 "vulcanized rubber

and thermoplastic rubber tensile performance test".

(2) determination of the intensity

   LX - A rubber hardness tester is an instrument for determination of

vulcanized rubber hardness. Requirements for rubber style:

thickness of not less than 6 mm,Width is not less than 15 mm,

the length is not less than 35 mm.

Test methods should be in accordance with

GB/T531 "vulcanized rubber shore A hardness test method".

(3) the air oven aging test of rubber

   Mainly use 402A heat aging test chamber,working temperature is 50°C—500°C,

the aging test is optional for 24 h, 48 h, 72 h,96 h, 144 h, or longer time.

(4) the compression permanent deformation measurement

   Test time from compress device into the timing starts at

high temperature box or low temperature box temperature,

the sample uniform compress to the fixed height.

It should be loose the fastener after the test,it can lay 30 minutes in the

standard environment, with a thickness gauge measuring sample recovery level.

Compression permanent deformation calculation:

-- -- -- -- - - the original height of the sample;

-- -- -- -- -- - the height of the sample after recovery;

-- -- -- -- -- - the height of the limiter.

(5) the determination of resistance to liquid

   It can according to the requirements of the vulcanized rubber technology,

test liquid can choose NO.1,NO.2 and NO.3 standard oil.
