Granulated Rubber

Updated: 2026-07-15

Overview

Granulated rubber, commonly referred to as crumb rubber, is a recycled material derived from scrap tires and other rubber products. The production process involves shredding and grinding rubber into small granules, which are then cleaned and sorted by size. This material is valued for its elasticity, durability, and cost-effectiveness, making it a popular choice for various industrial and recreational applications. Recycling rubber into granulated form helps reduce environmental waste and provides a sustainable alternative to virgin rubber. It is widely used in construction, sports, and manufacturing industries due to its ability to withstand heavy use and harsh weather conditions.

Physical and Chemical Properties

Granulated rubber exhibits excellent physical properties, including high elasticity and resistance to abrasion, making it ideal for surfaces that require cushioning, such as playgrounds and sports fields. Its density ranges from 1.1 to 1.2 g/cm³, and it is insoluble in water, ensuring longevity in outdoor applications. Chemically, granulated rubber is stable and resistant to many solvents and oils. However, it may contain trace contaminants from its original source, such as metals or fibers, depending on the recycling process. Proper testing and quality control are essential to ensure its suitability for specific uses.

Main Applications

Granulated rubber is extensively used in the construction of sports surfaces, including running tracks and artificial turf fields, where its shock-absorbing properties enhance safety and performance. It is also a key component in playground surfaces, providing a soft landing for children. In the construction industry, granulated rubber is added to asphalt to improve durability and reduce road noise. Industrial applications include the production of rubber mats, flooring, and vibration damping materials. Its versatility and affordability make it a preferred choice for many B2B buyers.

Safety and Storage

While granulated rubber is generally non-toxic, it may contain small amounts of contaminants from its original source, such as tire wires or chemicals. Handling with gloves is recommended to avoid irritation from sharp edges or dust. Storage should be in a dry, cool environment away from direct sunlight to prevent degradation. Proper ventilation is advised to minimize dust accumulation. Suppliers should provide material safety data sheets (MSDS) to ensure compliance with safety regulations.

B2B Procurement Guide

When procuring granulated rubber, B2B buyers should consider the granule size, purity, and source of the recycled material. Smaller granules are suitable for fine applications like artificial turf, while larger granules are better for playgrounds and athletic tracks. Verify the supplier's recycling process and quality control measures to ensure consistency and safety. Pricing varies based on granule size and purity, with bulk purchases often offering cost savings. Request samples and test reports to confirm the material meets your specific requirements.
