Rubber
(C₅H₈)n · Natural Rubber · Synthetic Rubber · Crumb Rubber · Rubber Granules
Rubber is an elastic, polymeric material derived from natural latex or synthetic monomers. It can be handled in multiple forms—crumb, shredded, pelletized, or sheets—depending on the stage of processing. The material is flexible, cohesive, and may become sticky or tacky under heat or pressure, making bulk handling challenging. KWS designs conveying systems that prevent buildup, maintain consistent flow, and minimize degradation or contamination.
Overview
Chemical Formula
Common Names
Common Forms
Applications
- Tire and automotive manufacturing
- Recycled rubber for playgrounds and athletic surfaces
- Sealants, gaskets, and industrial components
- Adhesives, coatings, and flexible materials
Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Crumb, Granules, Shredded, Pelletized Material |
| Bulk Density | 30–60 lb/ft³ (depends on size, type, and moisture) |
| Flow Behavior | Elastic, compressible, and prone to bridging or clumping |
| Abrasiveness | Low to Moderate some recycled rubber may contain metal or grit |
| Corrosiveness | Not Corrosive but can retain moisture and cause odor |
| Dust Potential | Moderate Low for crumb and pellets; moderate for fine ground rubber |
Handling Challenges
- Bridging and clumping due to elasticity and stickiness
- Material buildup and carryover on conveyor surfaces
- Heat generation causing tackiness or degradation
- Dust and odor control for ground or recycled rubber
- Difficulty in maintaining consistent feed rates due to compressibility
Summary
Rubber requires bulk handling systems designed for flexible, elastic, and sometimes sticky materials. KWS Manufacturing provides engineered conveying solutions—including screw conveyors, drag conveyors, and live bottom bins—that ensure reliable flow, reduce buildup, and prevent material degradation.
With extensive experience handling polymers, elastomers, and recycled materials, KWS ensures efficient, safe, and low-maintenance performance for rubber conveying systems.
