SKD®NVR

NVR is a rubber and plastic alloy rubber that is processed using Nitrile Rubber (NBR) and Polyvinyl chlorides (PVC) with IPN (Interpenetrating Polymer Networks Structure) technology in liquid state trough a chemical grafting reaction. The product has dual characteristics of both nitrile rubber and chloroprene rubber, which is not just a simple NBR/PVC compound material.

KEY ATTRIBUTES

CHEMICAL CHARACTERISTICS: NVR alloy rubber retains the ozone resistance property of Chloroprene rubber (CR) and the oil resistance property of Nitrile Rubber (NBR). Which can significantly improve the weather aging resistance, flame resistance, oil and fuel resistance and chemical resistance properties and other properties of the products. The products comply with REACH, SVHC, ROHS directives and manufactured through strict production process control, ISO: 016ZB12Q22258R0S. PHYSICAL PROPERTY: NVR rubber has outstanding processing property, anti slip property, no migration of color and coloring consistency performance, and excellent oil resistance, tear resistance, wear resistance, and chemical resistance properties (such as detergent, fat and oil, liquid acid alkaline etc.) PRODUCT APPLICATION: NVR can be used in Automobile fuel pipes and pipe external surface rubber, steel braided high pressure and ultrahigh pressure hose, wire and cable jacket, textile industrial roller/ picker, automobile seal, escalator handrail belt, printing and dyeing roller, seals and O-ring and automobile molded parts, aviation rubber products, rubber sheets, rubber belt, conveyer belt, safety boots, working shoes, mining shoes and other products industries.

PRODUCT PACKAGING

 

Ø Small packing of 25Kg/ Bag (Woven bag & EVA low melting point bag).

Ø Outer packing is divided into: 1. Pallet + woven bag + wrapping film; 2. Boxes + EVA low melting point bags.

Ø There are two functions to facilitate industrialization of automatic feeding system:

Ø The packaging materials is EVA material, which can be feed into the machine together with the packing bag, no need to remove packing materials.

Ø “P” means pellet form.  Which can reduce labor intensity on weighing and conveying, and fully implementation of mechanized conveyor feeding systems.

 

PRODUCT STORAGE

 

1The products should be stored in a cool, dry and ventilated environment, avoid direct sunlight, away from heat, storage temperature should not be higher than 40°C.

2Shelf life: 180 days from date of manufacture under proper storage conditions, expired products may continue to be used after inspections.

 

SAFETY
