How does resin glass transition temperature affect high-temperature performance of WPC flower boxes?

The glass transition temperature (Tg) of resin plays a critical role in determining the high-temperature performance of Wood-Plastic Composite (WPC) flower boxes. When exposed to elevated temperatures, the resin matrix in WPC softens as it approaches its Tg, leading to reduced structural integrity and dimensional stability. A higher Tg resin ensures better heat resistance, preventing warping, sagging, or deformation in outdoor applications.

For WPC flower boxes, selecting resins with an appropriately high Tg is essential for maintaining mechanical strength and durability in hot climates. Polymers like polyethylene or polypropylene with modified formulations can enhance thermal stability, ensuring the product retains its shape and functionality even under prolonged sun exposure. Understanding this relationship helps manufacturers optimize material selection for long-term outdoor use.
