Company Profile
Chengdu Longcheng High-Tech Materials Co., Ltd.
Longcheng High-tech is a company specializing in the production of low-viscosity PVB (polyvinyl butyral) resin—an advanced polymer material. Established in 2009, the company holds ISO 9001 and ISO 14001 certifications.
△ R&D Center
The company has developed products such as electronic-ceramic-grade PVB resin, food-grade ink PVB resin, PVB resin for protective coatings on new energy battery cells, and automotive-grade 3D printing PVB resin. Its PVB resin portfolio encompasses various product forms, including solvent-based, water-soluble, and emulsion types.
Our partners include leading companies in the MLCC sector; top global ink manufacturers such as DIC, Flint Group, and Siegwerk; as well as industry leaders in the new energy and bus manufacturing sectors.
In the field of electronic ceramics, we provide one-stop solutions encompassing product supply and technical services, working together to build a new landscape of autonomous and controllable supply chains in China.
Electronic-Ceramic Grade PVB Resin
Product Details
△ Electronic-grade PVB resin
1. Exhibits excellent compatibility with ceramic powders, solvents, and plasticizers, preventing agglomeration; produces smooth, defect-free cast films and reduces pinhole rates in dielectric layers.
2. Chloride ion content ≤100 ppm; features extremely low ionic residue and superior impurity control, ensuring high insulation and long-term reliability for electronic components while preventing electrochemical migration.
3. Offers an optimal thermal decomposition temperature window and a calcination residue of ≤0.01%; ensures complete binder burnout during sintering with minimal residual carbon, resulting in dense, defect-free ceramic bodies and improved breakdown voltage.
4. Demonstrates a linear relationship between viscosity and solid content, allowing for precise control of slurry formulations and more stable control of cast film thickness.
5. It exhibits excellent solubility; at 25°C, it dissolves rapidly in ethanol and various other solvents—much like instant coffee—with a controllable dissolution time typically ranging from 20 to 50 minutes.
