Two-Step TPU Prepolymer and Chain-Extension Solution
Coordinate a defined prepolymer stage with subsequent chain extension and TPU finishing.
Build the Process Around Your Product
Coordinate a defined prepolymer stage with subsequent chain extension and TPU finishing.
Product and material first
Start with the finished-product drawing, material system and acceptance requirements. The process route and equipment configuration are assessed together.
Capacity across the whole process
Define output with preparation, forming/reaction, curing, handling and inspection included. The slowest stage and product changes determine practical line capacity.
The proposal separates upstream prepolymer preparation from Haifeng multi-component metering/mixing and agreed downstream auxiliaries. Casting and extrusion stages are selected by the actual route.
From Preparation to Qualified Product
A planning sequence for the specified route. Final settings and acceptance conditions are established through material and part review.
Define the prepolymer route
Agree chemistry, prepolymer acceptance and whether preparation is supplied upstream or included in the scope.
Prepare or receive prepolymer
Specify conditioning, moisture control, hold limits and transfer interfaces.
Meter chain-extension feeds
Coordinate prepolymer, extender and optional additives with recipe and viscosity requirements.
Information Needed to Configure the Line
Provide these inputs so the equipment range, interfaces and validation plan can be defined.
| Design input | Information required |
|---|---|
| Prepolymer stage | Supplier or in-scope reaction unit, acceptance and storage window |
| Second-stage chemistry | Extender/additives, ratio and processing conditions |
| Output and changes | kg/h, grades, hold-up and transition plan |
| Downstream interfaces | Extrusion, filtration, pelletizing, water loop and drying |
Core Equipment and Integrated Interfaces
The proposal separates upstream prepolymer preparation from Haifeng multi-component metering/mixing and agreed downstream auxiliaries. Casting and extrusion stages are selected by the actual route.
Coordinate the Equipment With the Process
Evaluate repeatability, handling and acceptance across the full workflow.
Material-specific configuration
Component circuits, thermal control, mixing and receiving equipment are matched to the approved chemistry and processing window.
Defined interfaces
The proposal separates upstream prepolymer preparation from Haifeng multi-component metering/mixing and agreed downstream auxiliaries. Casting and extrusion stages are selected by the actual route.
Documented acceptance
The proposal defines trials, process records, inspection responsibilities and product-specific acceptance conditions.
