Not all foam materials perform the same. If you've explored packaging solutions, protective equipment, or even craft supplies, you've likely come across EVA foam and polyurethane (PU) foam. While they may appear similar at a glance, they serve very different purposes and offer distinct performance c

At TOPSUN, we recognize that the success of any construction project depends heavily on the materials selected—particularly for insulation, sealing, and acoustic control. That’s why our precision-converted polyethylene (PE) foam is engineered to deliver reliable, high-performance results across a wi

Every foam application places unique demands on material performance, often requiring a tailored balance of rigidity, flexibility, and cushioning.These properties work against one another. Rigidity provides resistance to deformation under continuous load, maintaining structural support. Flexibility
