Plastic Recycling TRIZ Cases
- Recycled Polyethylene Pipe Melt Flow Rate Control
Adding organic peroxides during extrusion reduces the high melt flow rate of recycled polyethylene, enabling precise viscosity control for pipe manufacturing.
- Formic Acid Stabilization of Amine Catalysts in Polyurethane Foam
Amine catalyst activity remains stable when formic acid is added to the polyol blend for foam manufacturing.
- PVC Solvent Screening via Swelling Score Equation
A solvent screening method uses a swelling score equation to identify suitable solvents for extracting polyvinyl chloride from waste materials.
- Transparent Multilayer Polymer Films with Refractive Index Matching
Refractive index matching in multilayer polymer films enables transparent packaging that incorporates recycled regrind without haze.
- Recycled Polyolefin Composition Compatibilizer for Film Properties
Heterophasic propylene ethylene copolymer compatibilizes recycled polyolefin blends for film production.
- Undercoat Agent Resin for Phase Separation Control
Specific resin components enable stable phase separation and surface control within a broader baking temperature margin.
- Polyolefin Composition Recycled Plastic Compatibilizer
Compatibilizer bridges recycled polyolefin contaminants with virgin matrix, stabilizing composition quality for high-end applications.
- Recycled PET to PBT Brightening via Purification
Depolymerizing and purifying recycled PET removes contaminants, achieving L* 94 brightness in PBT.
- Recycled Polyol Foam Quality via Polydispersity Control
Controlling recycled polyol polydispersity below 2 maintains foam quality while increasing the proportion of recycled raw materials.
- Recyclable Epoxy Composite via Degradable Curing Agent
A recyclable epoxy composite uses a degradable curing agent to enable fiber and resin recovery under mild conditions.
- Waste Plastic Pigment Extraction Using Shear Mixing
High shear mixing moves pigments to the surface for efficient solvent extraction, eliminating long processing times.
