Abstract
Overview
ISO 2303:2019 - "Isoprene rubber (IR) - Non-oil-extended, solution‑polymerized types - Evaluation procedures" - defines standardized laboratory methods for assessing general‑purpose solution‑polymerized, non‑oil‑extended polyisoprene (IR). The standard covers sampling, physical and chemical tests on raw rubber, a standard test formulation, and standardized equipment, mixing and processing procedures for evaluating vulcanization characteristics and physical properties of vulcanized test mixes.
Key topics and technical requirements
- Scope and sampling
- Applies to non‑oil‑extended, solution‑polymerized IR intended for general use.
- Laboratory sample: ~1.5 kg taken per ISO 1795.
- Physical and chemical tests
- Standard test formulation
- A reference compound is specified (total 144.95 parts by mass): IR 100, stearic acid 2.00, zinc oxide 5.00, sulfur 2.25, carbon black (N330) 35.00, TBBS 0.70.
- TBBS supply/quality requirements (powder form, initial insoluble matter
