Hualun Pisu (Suzhou) Co., Ltd. is a Sino-foreign joint venture with a total investment exceeding RMB 16 million. The company specializes in the research, development, production, and sale of various types of PU artificial leathers. Its product range includes garment leather, sofa leather, leather bags, ball leather, shoe leather, glove leather, automotive leather, and other specialized leathers. To support its high-quality output, the company is equipped with four dry-process lines, five wet-process lines, over ten advanced embossing machines, five dual-color printing presses, and multiple Italian ROLLMAC roll coaters and spray-painting systems.
TPU synthetic leather is a polymer material made from thermoplastic polyurethane elastomers. It utilizes an innovative and environmentally friendly production process that eliminates the use of solvents and heavy metals. As a 100% eco-friendly product, it offers excellent elasticity, breathability, and durability, making it an ideal choice for automotive interiors. This material combines multiple advantages in one, including high tensile strength, toughness, wear resistance, cold resistance, aging resistance, mildew resistance, and UV resistance.
What makes TPU particularly remarkable is its recyclability and biodegradability. It can be reused or naturally decomposed within 3 to 5 years when buried in the ground, making it a truly sustainable option. The introduction of TPU synthetic leather has significantly expanded the market for ecological alternatives in the artificial leather industry. It not only meets the growing demand for eco-conscious materials but also sets a new direction for the future of the industry, aligning with global sustainability goals.Achromat doublet lenses have significantly better optical performance than singlet lenses in visible imaging and laser beam manipulation applications.It consists of a positive low-index Crown Glass lens element cemented to a negative high-index Flint Glass lens element. The elements are chosen so as to cancel chromatic aberration at two well-separated wavelengths, usually in the blue and red region of the spectrum. Focal length is constant at those two wavelengths and focal length shifts are virtually eliminated across the visible wavelengths. One frequent use is to achieve diffraction limited focusing of a laser beam. Negative Achromat is typically used when there is a need to eliminate chromatic aberration. In addition to reducing chromatic aberration at the design wavelengths, spherical aberration and coma are greatly reduced. We always make our achromats as precise specifications and tolerances for uncompromising image quality upon customer's requirement.
