Product Description

PRODUCT NAME: 70 ºC PVC Flexible Insulation Material

PRODUCT CODE: T-PV003-JR70

General Description 
PVC insulation materials are mainly composed of PVC resin and various additives (such as plasticizers, stabilizers, fillers, etc.). PVC resin makes it have low conductivity and good insulation performance. The addition of additives can improve the processing performance and insulation performance of PVC resin, making it more suitable for the manufacture of various insulation products.

Features
Excellent insulation performance;
PVC cable sheath material  has Good processing performance;
Corrosion resistance;
Heat resistance;
Environmental protection;

Application
PVC insulated wires and cables are widely used in power transmission and distribution systems and building electrical systems;
Used in the manufacture of communication cables to ensure the normal operation of communication equipment;
The insulation layer of flame retardant flexible wires and cables with a voltage of 450/750V and below shall comply with PVC/D in GB5023 and JR-70 in GBT/8815-2008;

Package
Normal bag (25kg) or jumbo bag (650-850kg).

Appearance
70 ºC PVC flexible insulation materiall 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	Zone 6	Zone 7	Head	Die
TemperatureºC	140	150	155	165	165	170	170	175	175

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.
