1. Import rubber raw materials and main product categories.
100% imported raw materials, such as DuPont, Japan Daikin, Germany Lanxun and other well-known companies. High quality raw materials ensure the excellent performance of the sealing products. Taiwan XOK is a company that specializes in providing superior imported seals.
Main products:
A, O rings: rubber O rings of various materials, mainly NBR, HNBR, FKM/VITON, EPDM, FFKM, SIL, PU, CR, PTFE, etc.
B, ED rings, star rings, rubber balls, rubber flat gaskets, retaining rings, combined gaskets, pneumatic seals and non-standard rubber sundries;
C, cylinder: TC skeleton oil seal is the main part in stock, and other oil seals are also produced, such as Y-ring, U-ring, V-ring combination, Stern seal, Gray ring, dust-proof ring, water seal, etc.
Two, imported rubber packing standard and thread diameter
O-ring is a standard part, which is widely used. In the process of development, standards of various countries have gradually formed.
Typical examples are as follows:
1/ The national standard is divided into the old national standard and the new national standard. The old national standard is expressed by the outer diameter * line diameter of O-ring; the new national standard is expressed by the inner diameter * line diameter of rubber ring. At present, the domestic enterprises are mainly represented by the new national standard.
Old GB: GB GB1235-76--- diameter: 1.9, 2.4, 3.1, 3.5, 5.7, 8.6;
The new national standard: national standard GB3452.1-92--- diameter: 1.8, 2.65, 3.55, 5.3, 7;
2/ daily standard JIS B2401--- diameter is: 1.9, 2.4, 3.1, 3.5, 5.7, 8.4;
The R--- diameter of 3/ standard is 1.90, 2.70, 3.60, 5.33 and 6.99.
4/ American Standard AS568A, British standard BS 1806--- diameter: 1.78, 2.62, 3.53, 5.33, 6.99;
The diameter of 5/ de mark DIN3771 GB3452.1-92--- is 1.80, 2.65, 3.55, 5.30, 7;
6/ British standard BS 4518 Rui SMS 1586--- diameter: 1.6, 2.4, 3, 5.7, 8.4.
Three. Imported rubber packing has complete specifications and sizes.
Taiwan XOK is available in large quantities, with standard size basically available. Moreover, our company has strong technical force and can produce almost all kinds of inner diameter and diameter of O-ring in the market. Normally, even for non-standard sizes, there is no charge for die, unless the size is very large and the quantity required is relatively small, only a small amount of die fee will be charged. Internal diameter size: from 0.5 to 2000 mm (special specifications can also be customized); Line diameter size: 0.3, 0.5, 0.8, 1.0, 1.5, 1.78, 1.8, 2.0, 2.4, 2.62, 2.65, 3.0, 3.1, 3.5, 3.53, 3.55, 4.0, 4.5, 5.0, 5.3, 5.33, 6.0, 6.99, 7.0, 8.0, 9.0, 10, 12, 14, 15, etc. All types of O-rings are suitable for medium: oil, water, steam water, strong acid, strong alkali, freon, ethylene glycol, etc. Limit temperature: -60-250 C, pressure: 0-35 MPa; If long-term use temperature is required to be 250 C, perfluorine O-ring is recommended. It can withstand 1600 kinds of media, and its performance is excellent. The disadvantage is that the price of perfluorine is too expensive.
