Why Shield

Our Secret to Success - Shield Membrane: At Shield, we utilize Thermoplastic Polyurethane (TPU) to construct our Shield Membrane. This material, first invented in 1937, has become a staple material in the outdoor and sports industries due to its impressive properties such as high elongation and tensile strength, elasticity, and resistance to various substances like oil, grease, solvents, and chemicals. TPU's segmented structure, consisting of hard segments (HSs) and soft segments (SSs), offers unique properties. As temperatures rise, the soft segments expand, creating tiny pores that allow water molecules to pass through. Conversely, when the weather is cold, the SSs contract, closing the pores and increasing the material's strength and insulation properties, helping to keep wind and dirt out and extending the lifespan of the cover. Our specialized laminating process bonds TPU to the outer and inner shell, creating a highly effective Shield outdoor cover.
