Product Description

PRODUCT NAME: 70 ºC PVC Insulation Material

PRODUCT CODE: T-PV004-J-70

General Description 
Base on PVC resin,  this product is PVC insulation material made by mixing, plasticizing, and granulating with plasticizers, stabilizers, and other additives.

Application
Instrument communication cables, insulation layer for cables 600/1000V and below, in accordance with PVC/C in GB5023 and J-70 in GBT/8815-2008.

Appearance
70 ºC PVC insulation material should be made into uniformly sized particles with a particle size of 4mm × 4mm × 3mm, or ф 4× (2-4) mm. Good plasticization, uniform color, and no obvious impurities.

Color
The color is determined through negotiation between the supply and demand parties.

*Note: 1  The extruded lines are smooth, and no more than 3 floating points with a diameter ≥1.0mm are allowed within 1 meter.No particles ≥ 3.0mm are allowed. 2  All products shall undergo initial inspection upon startup, including appearance, color, density, etc. 3  If the first sample test fails, a retest is required, and the result of the second test is the judgment standard.

Processing
Using a general extruder for processing, L/D≥20
Adjust appropriately according to the equipment and extrusion status.

The following temperature profile of extruder is recommended:

Zone	Zone 1	Zone 2	Zone 3	Zone 4	Zone 5	Head	Die
TemperatureºC	120	130	135	145	155	160	160

Storage and transport
It should be packaged in moisture-proof packaging, with polyethylene film bags for the inner bag and kraft paper composite bags for the outer bag, with a net weight of (25.0 ± 0.2) kg per bag. Other packaging methods agreed upon by both the seller and the purchaser are allowed.
During the transportation of the product, it should not be damaged by abnormal conditions such as sun, rain, and immersion in water. It should be kept clean, dry, not contaminated, and the packaging should be kept intact.
The product should be stored in a clean, cool, dry, and ventilated warehouse, and the storage period should not exceed six months from the date of production.
