Background technique
EPDM is the terpolymer of ethylene, propylene and non-conjugated diene hydrocarbon.Alkadienes has special structure, only
Have could being copolymerized for one of two keys, unsaturated double bond primarily as interlinkage at.Another unsaturated will not become polymerize
Owner's chain can only become avris chain.The principal polymeric chain of EPDM is fully saturated.This characteristic makes EPDM
Heat, light, oxygen, especially ozone can be resisted.EPDM be substantially it is non-polar, have to polar solvent and chemicals
Resistance, water absorption rate is low, has good insulation characterisitic, has high corrosion resistance and splendid chemical stability, and resistance to ozone is old
Change, heat oxygen aging resistance.
The products characteristics of polyester line:
1, UV ultraviolet stability: polyester line has the very long service life, is more than 30 to transparent polyester line in south of europe
Outdoor application test in a month shows that the tensile strength of polyester line is reduced less than 3%, and the strength reduction of black polyester line is more
It is few.This means that polyester line service life under various greenhouse experiments (glass, plastic film etc.) and outdoor conditions is very long.
2, thermal stability: polyester line can keep its mechanical property in the case where -40 DEG C~70 DEG C of environment temperature completely
It is constant with geometric dimension.
3, tensile properties: compared with nylon wire, the extensibility of polyester line is lower, therefore can easily be opened rapidly
Tightly, and once it is tensioned, polyester line will keep this tensioning state without being tensioned again again.This characteristic of polyester line
From other intensity it is lower, need the nylon wire of re-tensioning or monfil line different.
4, permanent smooth: polyester line is non-hygroscopic, and therefore, after many years use, surface is still bright and clean as before, goes out without burr
It is existing.The surface smooth finish of polyester line has positive effect to the sunshading and thermal insulating curtain of its support, avoids to sunshading and thermal insulating curtain
Abrasion.
5, surface is smooth: the continuous and derivable on surface mitigates the abrasion to sun shading material.
6, performance is stablized: using under normal condition, size changing rate is minimum, after being tensioned the product in use
It will not be sagging
Both the above product is widely used, because of its excellent stability and economy instead of big portion in many products
Conventional raw materials are divided to be changed to the third glue of second by original neoprene and butadiene acrylonitrile rubber such as the hydraulic-brake hose in automotive hose.Cause
Polyester fibre surface is very smooth, contains group, and activity is low, is by containing a small amount of-OH, surface tool in molecular weight tail on surface
There is hydrophobicity, the bonding between rubber is extremely difficult, it is also difficult to handle.Traditional solution is smeared again outside braided fabric
One layer of adhesive, but its solvent is mostly to contain toluene and formaldehyde, endangers the health of operator.
