Overview
Alcryn® ALR-7083NAT is still capable of being processed through injection molding techniques, however; this grade performs best for extrusion processes where reduced die drool is critical for thin-wall sections at higher output. Encompasses all the classic Alcryn® properties such as high flexibility, Shore A 61 hardness, ozone resistance, and compression set while offering smoother extrusion benefits and reduced maintenance downtime.

Melt Processable Rubber
Features & Benefits
- Internal lubricant package enables cleaner and longer extrusion runs
- Optimized for high-output, thin-wall profiles and complex shapes
- True elastomeric properties for rubber-like feel without vulcanization
- Excellent environmental resistance to ozone, UV, chemical or oil
- Reliable performance from extreme cold to elevated heat
- Maintains strength and flexibility under heat, oil exposure, and dynamic loads
Problems Solved
Time-consuming, expensive curing steps in rubber manufacturing
Challenges in reusing or recycling rubber waste
Insufficient resistance to oils, fuels, and harsh chemicals
Premature aging from ozone, UV, and outdoor exposure
Restricted performance across extreme temperatures
Die drool and poor surface finish for high-output extrusion
Inefficient processing for thin-wall profiles
Die buildup and inconsistent flow increase cleaning cycles
