Solution Overview

Problem

Conventional flooring materials, such as those using waste tire chips or recycled rubber, often release harmful substances like VOCs and have low adhesiveness, leading to reduced durability and elasticity over time, making them unsuitable for environmentally friendly and long-lasting applications.

Innovation Solution

A composition for flooring incorporating coconut fiber with acrylonitrile-butadiene latex, vulcanizing agents, zinc oxide, antioxidants, and calcium carbonate, which is applied and compressed to create a durable, weather-resistant, and VOC-free surface without the need for organic binders.
