Hualun Leather Plastic R&D TPU Synthetic Leather

Hualun Leather Plastic R&D TPU Synthetic Leather 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, manufacturing, and distribution of various types of PU artificial leathers. Their product range includes garment leather, sofa leather, leather bags, ball leather, shoe leather, glove leather, automotive leather, and other specialized materials. To meet the growing demand for high-quality synthetic leather, the company has invested in advanced production facilities, including four dry-process lines, five wet-process lines, over ten high-end embossing machines, five dual-color printing presses, and multiple Italian ROLLMAC roll coaters and spray-painting systems. TPU Synthetic Leather is an innovative material made from thermoplastic polyurethane elastomers. It uses a completely new and environmentally friendly production process that eliminates the use of solvents and heavy metals. As a 100% green product, it offers excellent elasticity, breathability, and durability. It has become a top choice for automotive interior applications due to its superior performance and eco-friendly nature. What sets TPU apart is its sustainability. This material can be recycled and, when disposed of, it can naturally degrade within 3 to 5 years. It combines numerous advantages such as high tensile strength, excellent toughness, wear resistance, cold resistance, aging resistance, mold resistance, and UV resistance. These properties make it a highly versatile and durable option for a wide range of industries. The introduction of TPU Synthetic Leather has significantly expanded the market for ecological synthetic leather and represents a major step forward in the sustainable development of the artificial leather industry. With its environmental benefits and superior performance, it is shaping the future of eco-conscious material innovation.

Holographic Grating

China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, reflective gratings,holographic gratings,concave gratings etc. to meet different needs. Maximum ruled area is up to 300x300mm2 for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from 20 grooves per millimeter to 2400 grooves per millimeter, wavelength from 0.2 micron to 25 microns. 

They are widely used for applications in optical communications,biotechnology, colorimetry,chromatography,and medical instrumentation.

Handling Gratings: Gratings require special handling, making them prone to fingerprints and aerosols. Gratings should only be handled by the edges.
