Jiangsu BESD New Materials Co., Ltd. As a professional Chinese OEM/ODM polyester resin supplier for HAA based formulations and a customized polyester resin factory for HAA based formulations, we follow strict standards and processes for the quality inspection of polyester resin mixed formulations after HAA based formulations are cured to ensure excellent and stable product quality. The following are the main steps we take for quality inspection:
1 Raw material inspection:
All raw materials for polyester resin for HAA based formulations are strictly screened and inspected to ensure that they meet industry standards and company quality requirements. Check the batch, production date, manufacturer and other information of the raw materials to ensure that the source is reliable.
2 Production process control:
Use advanced automated production lines to ensure that parameters such as temperature, pressure, stirring speed, etc. in the production process are accurately controlled to achieve the best production results. Monitor various indicators in the production process in real time to promptly detect and correct any deviations that may affect product quality.
3 Post-curing performance test:
Acid value detection: Use professional acid value determination instruments to detect the acid value of the cured polyester resin to ensure that it meets product specifications.
Viscosity test: The viscosity of the cured polyester resin is measured by a viscometer to evaluate its fluidity and processing performance.
Curing time test: Under different temperature and humidity conditions, the curing time of the polyester resin is tested to ensure its applicability in various application environments.
Mechanical property test: Mechanical property tests such as tensile strength, flexural strength, and impact strength are carried out to evaluate the mechanical properties of the cured polyester resin.
Heat resistance test: The thermal stability of the polyester resin is tested under high temperature conditions to ensure that it can maintain stable performance under high temperature conditions.
4 Environmental adaptability test: The cured polyester resin samples are placed under different environmental conditions (such as high temperature, low temperature, humidity, salt spray, etc.) to evaluate their durability and stability under these conditions.
5 Customer feedback and continuous improvement: Collect and analyze customer feedback, and conduct timely investigations and improvements on quality issues raised by customers. Continuously optimize production processes and formulas to improve product quality and performance.
As an enterprise that has passed ISO:9001 quality management and ISO:14001 environmental management system certification, we always put product quality first and are committed to providing customers with high-quality and high-performance polyester resin products.
