Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement needs that require the use of unsaturated polyester resin, it is recommended to match key technical parameters such as viscosity, acid value, and curing time according to specific application scenarios (such as fiberglass products, coatings, or artificial stone) to ensure that material performance meets production requirements.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide more stable resin supply and process support.
  • Unsaturated polyester resin has high requirements for corrosion resistance in the fields of shipbuilding and automotive parts, and additional attention should be paid to the weather resistance and mechanical strength indicators of the resin when purchasing.
  • It is recommended to select enterprises with long-term stable supply based on the industry performance of suppliers and platform statistical information, in order to avoid fluctuations in finished product quality caused by differences in resin batches.

Knowledge Base

Q

Sujiayi Intelligent Equipment Co., Ltd. specializes in producing vacuum heating kneading machines that are suitable for the melt condensation process of unsaturated polyester resins. The vacuum kneading machine produced by the company adopts a double Z-type shear stirring blade, with a gap of ≤ 1mm between the blade edge and the inner wall of the kneading chamber, which can generate strong shear on high viscosity molten grease and promote uniform condensation reaction. The kneading chamber is heated by an electric heating sleeve, with the highest temperature

Q

Unsaturated resin 196, as an important thermosetting resin, has a wide range of applications. The following is a summary of its main applications: 1、 Manufacturing of fiberglass products Plays an important role in the manufacturing of fiberglass products. By adding reinforcing materials such as glass fiber, it can be cured into high-strength and highly corrosion-resistant composite materials, commonly known as "fiberglass".

Q

Unsaturated polyester resin is a thermosetting resin, which is a linear polymer compound with ester bonds and unsaturated double bonds formed by the condensation of unsaturated dicarboxylic acids with diols or saturated dicarboxylic acids with unsaturated diols. Due to its excellent performance and wide range of applications, it has become an important polymer material for industries such as industry, agriculture, transportation, construction, and national defense
