Premium GRS ABS Products from a Leading Manufacturer

Based on high-molecular physics modification, efficient odor removal technology and micro-micron melt filtration technology, Synsoly has overcome the problems of brittleness, poor toughness, severe thermal degradation, significant surface shrinkage and obvious color difference of traditional recycled ABS. Our GRS ABS Products can be customized within the range of 20% to 100% as per customer requirements. Our GRS ABS Products can be customized as needed within the range of 20% to 100%. We have a complete official GRS supply chain traceability system, helping global brands seamlessly replace high-carbon-emission petroleum-based Virgin ABS. It is widely applied in fields such as consumer electronics casings, household appliance frames, automotive interior parts, high-end toys and smart bathroom components.

Product structure

Modified particle morphology: cylindrical or spherical granules, with a uniform particle size ranging from 2.5mm to 3.5mm. There are no agglomerations or dust. The surface is smooth. According to customer requirements to prepare high gloss black, translucent, milky white and a variety of designated Pantone brand color.

Structure of injection molding parts/molding products: full mold filling, uniform wall thickness distribution, no obvious shrinkage, white top, air or water pattern on the surface, dense interior, with excellent structural rigidity.

Manufacturing process flow

1. Utilizing near-infrared (NIR) photoelectric sorting machines and density sedimentation method, precisely separate impurity resins such as PS, PC, and PP, ensuring the purity of the ABS base material to be above 99%.

2. Through powerful crushing and hot alkaline cleaning, remove surface residual paint and adhesives; Then it enters the high-temperature vacuum devolatilization and deodorization system, which greatly reduces the small-molecule odor inside the material.

3. During the melting extrusion process of the material, through high-precision continuous screen changer (with filter mesh numbers ranging from 100 to 150), completely intercept and remove tiny particles and carbonized impurities.

4. Add proprietary compatibilizers, antioxidants and impact modifiers (such as ultra-high rubber content SAN/ABS toughening agents) to repair the molecular chain breaks of the recycled resin and restore its original toughness.

5. The modified granules enter the tens-of-ton large-scale homogenization premixing tank for long-term stirring, eliminating fluctuations in MFR and color difference between batches, ensuring highly consistent delivery quality.

Product features and advantages

The impact strength, tensile strength and heat distortion temperature of SynsolyGRS ABS products fully meet the standards of industrial-grade raw materials. They are produced using a large-scale homogenization and premixing process, with the color difference between batches strictly controlled within the range of ΔE < 0.8. The melt index fluctuation is less than ±10%. The appearance and texture are excellent, with low odor. They have undergone multiple top-space deodorization and micron-level filtration treatments, resulting in high surface glossiness, very few black spot impurities, and no pungent odor. They are suitable for high-end electronic and home appliance shells.

Maintenance and Storage Methods

1. Please store the unopened packaging in a cool, dry, well-ventilated indoor warehouse without direct sunlight exposure to prevent the aging of the outer packaging and the surface of the particles due to ultraviolet radiation.

2. Unused particles should be immediately sealed with the inner PE film to prevent dust from the workshop from entering and causing injection marks.

3. It is recommended to follow the "First In, First Out" (FIFO) principle. The optimal storage and usage period for the materials is 12 months from the date of manufacture.
