Plastic Resins
Green Earth supplies virgin GPPS and recycled PS pellets for XPS extrusion, injection molding, thermoforming and other industrial applications, with grade-based material selection and technical supply support.
Virgin GPPS and Recycled PS Pellets for Industrial Processing
Green Earth supplies virgin GPPS and recycled polystyrene pellets for qualified XPS board extrusion, injection molding, thermoforming and other industrial plastic processing applications. Material selection should be based on grade-specific performance data, processing method, color, purity, target properties and end-use requirements.
For B2B buyers, Green Earth can coordinate material sourcing according to required grade, quantity, packaging and technical documentation.
Available Resin Products
Virgin GPPS Resin
GPPS Virgin Resin is available for qualified extrusion, injection molding and thermoforming applications requiring consistent material properties and stable processing performance.
General-purpose and transparent grades can be evaluated according to melt flow rate, optical properties, thermal performance and the requirements of the finished product.
Recycled PS Pellets
Recycled Polystyrene Resin provides a recycled material option for suitable XPS and general PS processing applications.
Recycled material should be evaluated based on feedstock source, purity, moisture, contamination, melt flow characteristics, color and batch consistency. Production trials may be required before approving a grade for continuous manufacturing.
Resin Technical Data to Publish
Each resin grade should be supported by clear technical information so purchasing and engineering teams can evaluate material suitability.
| Specification | Publish by Grade |
|---|---|
| Grade / Application | Grade code and recommended process/end use |
| Melt Flow Rate | Test method, condition and unit |
| Density / Bulk Density | Test method and unit |
| Vicat / Heat Deflection | Test method and condition |
| Mechanical Properties | Tensile, flexural and impact data where applicable |
| Optical Properties | Transmittance, haze and color for transparent grades |
| Purity | Moisture, ash, residual monomer and contamination limits |
| Supply | Color, packaging, MOQ, lead time and annual capacity |
| Documents | TDS, SDS, batch COA and compliance declarations |
Resin Selection by Application
The appropriate polystyrene grade depends on the processing method and finished-product requirements.
| Application | Key Selection Factors |
|---|---|
| XPS Board Extrusion | Melt flow, purity, thermal stability and formulation compatibility |
| Injection Molding | MFR, impact performance, dimensional stability and thermal properties |
| Thermoforming | Melt behavior, thermal performance and sheet-processing characteristics |
| General Plastic Extrusion | Processing stability, melt flow and thermal properties |
| Recycled PS Processing | Purity, moisture, contamination, MFR and batch consistency |
For XPS manufacturing projects, resin selection can be evaluated together with our XPS Board Production Line.
For downstream processing requirements, see our Plastic Extrusion Machinery.
For projects involving PS waste recovery and recycled pellet production, see our Plastic Recycling Pelletizing Equipment.
