Core Product Advantages
Excellent Mechanical Strength and Rigidity
Huarun CR-8818 PET resin features exceptional tensile strength and structural rigidity, far superior to conventional polyethylene materials. Its stable molecular chain structure endows the material with strong resistance to stretching, impact and deformation. This core advantage enables products made from this resin to maintain stable structural performance under long-term stress, extrusion and external impact. It is particularly suitable for manufacturing high-strength packaging containers, structural consumer goods and industrial protective parts, effectively avoiding cracking, deformation and damage during storage, transportation and daily use. The optimized molecular polymerization process ensures uniform mechanical properties of each batch of products, guaranteeing consistent finished product quality.
Superior Processability and Molding Stability
This PET resin boasts excellent fluidity, uniform crystallization performance and low molding shrinkage, adapting to multiple mainstream processing technologies including injection molding, blow molding and extrusion molding. During processing, Huarun CR-8818 can melt evenly and flow smoothly into mold cavities, realizing high-precision molding with stable wall thickness and smooth surface texture. It effectively reduces defective rates in mass production and shortens molding cycle, greatly improving production efficiency and lowering overall manufacturing costs. In addition, the material supports modified compounding and recycled material blending, which is compatible with sustainable production modes and meets the environmental protection and cost-control needs of modern enterprises.
Outstanding Barrier & Transparent Performance
Huarun CR-8818 has excellent gas barrier and moisture-proof properties, which can effectively isolate oxygen, carbon dioxide and moisture, protecting the internal contents from oxidation, deterioration and moisture erosion. Meanwhile, the material features high light transmittance and low haze, with excellent visual performance. This unique combination of barrier and transparent properties makes it ideal for food, beverage and daily chemical packaging, ensuring product freshness and extending shelf life while presenting a high-grade appearance of finished products.
Wide Application Versatility
With balanced mechanical properties, stable chemical resistance and excellent molding performance, Huarun CR-8818 covers a full range of application scenarios across multiple industries. It can be flexibly applied from lightweight transparent packaging products to high-rigidity industrial parts, realizing multi-scene application of a single raw material. This greatly simplifies customers’ raw material inventory management, reduces procurement and storage costs, and improves the flexibility of production line scheduling.

Processing & Storage Guidelines
Huarun CR-8818 PET resin has strict processing requirements due to its polyester material characteristics. Before processing, strict drying treatment is mandatory: dry the pellets at 120–160°C for 4–6 hours to control the moisture content below 0.02% and prevent hydrolysis and bubble defects during molding. The optimal processing temperature is controlled within 240–280°C, with mold temperature maintained at 40–80°C to ensure uniform crystallization and stable molding quality.
For daily storage, place the resin in a dry, cool and ventilated environment with a temperature of 10–35°C, away from direct sunlight, high-temperature heat sources and humid air. Keep the material sealed in original packaging at all times to prevent moisture absorption, dust contamination and impurity mixing, so as to retain the original processing performance of the resin.
