How does the inclusion of recycled rubber particles in resin composites reduce planter weight?

The inclusion of recycled rubber particles in resin composites significantly reduces planter weight through several mechanisms. First, rubber particles are inherently less dense than traditional filler materials like sand or stone, lowering the overall density of the composite. Second, the porous structure of rubber creates air pockets within the resin matrix, further decreasing weight without compromising structural integrity. Additionally, rubber's elasticity allows for thinner, lighter designs while maintaining durability. This sustainable approach not only reduces material costs but also minimizes environmental impact by repurposing waste rubber. Lightweight planters made with this composite are easier to transport and install, making them ideal for urban gardening and commercial landscaping applications.
