Application

Ethylene Type (Vinyl Resin)

 

Type V

It has strong resistance to corrosion. It is resistant to solvent of acids, alkali, and salt or the alternate acid and alkali environment in a long period of time, and the usage temperature is -50℃~110℃.The velocity of inflaming retarding is Grade One of ASTM E-84 ,and the flame spreading index is below 25

Often used in strongly corroded environment with the solvent of acid, alkali, salt, etc.

 

High inflaming retarding ethylene type

 

Type HV

It has strong resistance to corrosion. It is resistant to solvent of acids, alkali, and salt or the alternate acid and alkali environment in a long period of time, and the usage temperature is -50℃~ 110. The inflaming retarding performance is better than the common ethylene type grating and the velocity of inflaming retarding is Grade One of ASTM E-84, and the flame spreading index is below 10.

Often used in the environment that requires inflaming retarding and that has serious acid and alkali corrosion.

 

ISO resin type

 

Type I

It has strong resistance to corrosion. It is resistant to acid of middle density, alkali, various salts environment, and the usage temperature is -50℃~90℃,the highest temperature is 105. The velocity of inflaming retarding is Grade One of ASTM E-84 ,and the flame spreading index is below 25.

Often used in environment of high acid corrosion or normal alkali corrosion.

 

No-Poison resin type

 

Type F

ISO no-poison resin type has the same strong resistance to corrosion as ISO resin type, the usage temperature is -50℃~90℃, and the highest temperature is 105℃.

Often used in meat and food processing factories, and waterworks

ORP resin type

 

Type O

It has the normal resistance to corrosion. It is resistant to seawater, weak acid and atmospheric aging environment, the usage temperature is -50℃~60℃, and the highest temperature is 100℃. This is the economical type. Compared with the traditional steel grating, aluminum grating and wood grating, its corrosion resistance is better though its corrosion resistance is weak in all of the resin types. The velocity of inflaming retarding is Grade One of ASTM E-84, and the flame spreading index is below 25.

Often used in environment of normal corrosion, seawater corrosion, weak acid corrosion and atmospheric aging corrosion.

E-Roving

 

2400TEX

4800TEX

With strong resistance to corrosion, it can be combined firmly with matrix resin, which endows the products with excellent mechanic capability and corrosion resistance.

Environment that requires high intensity and corrosion resistance

C-Roving

 

2400TEX

It has good permeability, and combines itself firmly with matrix resin. It dos well in resistance to acid.

Non-Alkalescence corrosion resistance surroundings
