Pvc coupling is Conduit Coupler
Trait: Fireproof and Resist Compression
1) Installation during the process of construction, electrical equipment, electrical components, etc.
2) High strength and toughness, are suitable for all kinds of bad conditions, and not easy distorted.
3) With no smell attracting rodent, avoid suffering from biotic attack.
4) No poison no second pollution.
5) Free from weakness caused by rusting, weathering and chemical actions.
6) Good insulation property, good fire- resistant, good combustion-resistance.
7) Protects wire and cable from easy damage.
8) PVC connector are used as surface mounting, control box, junction box, switch box or general service box and pipe.
PVC is the amorphous polymer, no obvious melting point, heating to 120 ~ 150 ℃ plasticity.Due to its low thermal stability, containing a small amount of HCl release at the temperatures, prompting them to further decomposition, reason must join the alkali stabilizer and HCl and inhibit the catalytic cracking reaction.Pure PVC rigid products, need to add the right amount of plasticizer can make the soft for different products still need to join, such as ultraviolet absorbent, fillers, lubricants, pigment, the use of fertilizer to become good PVC products such as mould inhibitor performance.As with other plastic, resin performance determines the quality of products and the processing conditions.For PVC resin performance related to the processing, grain size, heat stability, molecular weight, fisheye, loose density, purity and foreign material, porosity.Of PVC paste and paste viscosity and gel performance, etc., all should try to determine, easy to master the processing conditions and quality of products.
