NR SHEETING HIGH PERFORMANCE

Overview

Features

Natural rubber, para quality, translucent, with excellent mechanical properties.

Benefits

Functionality Comfort Service life Economy

Applications

Gaskets or washers cutting and manufacturing of pieces for general purpose applications in contact with:
- maximum temperature 50°C: water, water washing, alkaline and salt solutions, acids and oxidizing non oxidizing, alkali base concentration ≤50%, non food alcohol
- maximum temperature 20°C: acetones

Cutting into skirtboard and scrappers for conveyors belts, rubber sleeves, etc.

Mineral processing equipment linings, such as operating cyclones, hydrocyclones and sand treatment processes.

Advantages

Very good mechanical properties (tensile strength, tear resistance,etc.) and at the same time, easy material to work with
Good properties to support high mechanical strains
Great elasticity allowing important deformations
Resistance to fine grained particles wear projection (sand, blasting)
Good electrical properties
Good resistance to acids, bases and salts
Good ratio quality/price
