When shopping for a phone case, many users only focus on appearance while ignoring materials, which directly determines the protection effect, service life and using comfort of the product. As a brand that has been deeply engaged in mobile phone accessories for many years, Longwin always regards material selection as the foundation of product quality. We insist on using eco-friendly, safe and high-performance raw materials, and combine exquisite production technology to create phone cases with outstanding quality. Today we will take you to learn about the core materials and craftsmanship behind Longwin phone cases.
TPU is one of the most widely used materials in Longwinโs classic phone case series. We select high-purity environmentally friendly TPU raw materials imported from regular suppliers, which is different from inferior recycled materials on the market. High-quality TPU features good flexibility, elasticity and toughness. It can bend freely without deformation or cracking, and can quickly restore its original shape after being squeezed. This material has excellent shock absorption performance. When the phone falls, the TPU case can disperse impact force effectively, reducing the damage to the phone body. Moreover, our TPU materials are odorless and non-toxic, meeting international environmental standards. Even if you hold the phone close to your face for a long time or carry it with your kid, you do not need to worry about potential health risks. The surface of TPU cases is treated with anti-yellowing technology, which effectively delays aging and yellowing, so the case can keep a new look for a longer time.
In addition to soft TPU, hard PC material is also applied to many Longwin combined protective cases. PC material is famous for its high hardness, strong compression resistance and scratch resistance. It can resist friction from daily sharp objects such as keys and metal ornaments, preventing the phone shell from leaving ugly scratches. We combine TPU and PC materials organically in dual-layer protective cases: the inner soft TPU fits the phone closely for shock absorption, while the outer hard PC bears external friction and collision. This composite structure integrates the advantages of two materials and greatly improves the overall protection level. All PC materials used by Longwin have passed strict hardness and durability tests, and will not become brittle or break after long-term use.
Surface processing technology is also a key part that affects the using experience. Longwin adopts a variety of mature surface treatments for different series of products. The matte frosted process can eliminate fingerprints and oil stains, bringing a delicate and non-slip touch; the high-gloss polishing process makes the case bright and exquisite, with strong visual appeal; the anti-slip texture carving on the side optimizes the holding feel and avoids slipping. Every production link is strictly supervised by our quality control team, from material cutting, mold forming to surface printing and edge trimming. We reject rough burrs, uneven cutting and loose fitting problems.
A good material creates a good product, and fine craftsmanship wins usersโ trust. Longwin never pursues low cost at the expense of quality. Every phone case we launch is a careful work made of premium materials and elaborate technology. If you are tired of cheap phone cases that turn yellow easily, break quickly and have peculiar smells, try Longwin products. We use reliable materials and sincere craftsmanship to bring you a safe, comfortable and durable phone protection solution.
