Black HNBR 90 shore Hardness O Ring Hydrogenate Nitrile Seals for Air conditioning​

Introduction for O Ring

1.The O-ring is an annular seal having an O-shaped cross section, the size of which is determined

by the inner diameter ID and the wire diameter CS.

2.O-ring size calculation: outer diameter = inner diameter + 2 x wire diameter (OD = ID + 2x CS).

3.The purpose of using O-ring seals is to prevent leakage and loss of liquids or gases.

4.O-rings are the most commonly used type of seal because of their simplicity, convenience, and

small installation space. As long as the groove design and material selection are correct, and the

operating conditions are within the temperature range of the rubber material, the seal can have a

long-term sealing effect in the static or dynamic seal.

HNBR Rubber Features:

Hydrogenated Nitrile Butadiene Rubber (HNBR), also known as Highly SaturatedNitrile

(HSN), is special class of nitrile rubber (NBR) that has been hydrogenated to increase

saturation of the butadiene segment of the carbon polymer backbone. Subsequent

improvements to the material properties, over that of a nitrile rubber (NBR), include

greater thermal stability, broader chemical resistance, and greater tensile strength.

HNBR is classified by ASTM as a DH-type polymer. This classification indicates 150ºC

service temperature as well as less than 30% swell in IRM 903 oil. HNBR can be formulated

to meet application temperatures ranging between -50°C and 165ºC.

We can supply material: Silicone, NBR, EPDM, FKM&FKM, NR, HNBR, SBR, Neoprene, PU,

FFKM, etc . You can choose material as your requirements :

Quality Control

Material Inspection:Storage of all raw materials before the test, and issue a report on the corresponding

material properties, compared with raw material's own property report, two reports property values is

consistent, can put in storage.

Model Inspection:After the mold development or mold cleaning finished on the machine, we will test all

the specifications of the mold to ensure that each cavity of the product specifications and quality.

Production Inspection:The production process of the product inspection personnel timing semi-finished

product inspection, ensure the quality of the rationality of technology, defective rate control in a reasonable

range.

Quanlity Control:The quality inspection department will conduct a sampling inspection of each batch of

products Production Full Inspection:The optical inspection machine can ensure the appearance and dimension

of the product are 100% qualified.
