PLC Controlled Automatic Temperature Control EPDM/Butyl Rubber/NR Cold Feed Extruder
Here’s a detailed comparison of cold feed extruders for processing EPDM, Butyl Rubber (IIR), and Natural Rubber (NR), including key technical considerations and application-specific requirements:
| Parameter | EPDM | Butyl Rubber (IIR) | Natural Rubber (NR) |
|---|---|---|---|
| Extruder Type | Typically cold feed (long L/D) | Cold feed (modified design) | Cold feed (common) or hot feed |
| Screw Design | - Long L/D (12:1 to 20:1) - High compression (1.8:1–2.5:1) - Mixing sections for uniformity |
- Medium L/D (10:1–15:1) - Moderate compression (1.5:1–2:0:1) - Low shear to avoid degradation |
- Standard L/D (10:1–16:1) - Moderate compression (1.6:1–2.2:1) - Good mixing for NR compounds |
| Temperature Control | - Precise cooling needed (EPDM is heat-sensitive) - Barrel zones: 60–100°C |
- Low processing temps (70–90°C) - Avoid overheating (IIR degrades easily) |
- Higher temps (80–110°C) - NR flows better when warm |
| Feed System | - Forced feed (EPDM is sticky) - Pre-breaker rollers optional |
- Sticky material: Ram feeder or grooved feed throat | - Standard feed hopper (NR is easy to process) |
| Key Challenges | - Poor melt flow (needs high pressure) - Air entrapment (degassing needed) |
- Low permeability (traps air) - Slow extrusion rates |
- High viscosity (needs proper screw design) - Risk of scorching |
| Typical Products | - Automotive seals - Roofing membranes - HVAC gaskets |
- Tire inner liners - Pharmaceutical stoppers - Vibration dampers |
- Tire treads - Conveyor belts - Rubber mats |
| Special Requirements | - Vacuum extruder for air removal - Smooth barrel surface |
- Slow screw speed (avoid shear heat) - Polished screw/barrel |
- Anti-stick coatings (NR tends to adhere) |
EPDM Extruders:
Require high-pressure screws and vacuum degassing.
Need precise cooling to prevent scorching.
Butyl Rubber (IIR) Extruders:
Low-shear design critical (IIR degrades easily).
Slow extrusion speeds improve product quality.
Natural Rubber (NR) Extruders:
Standard cold feed extruders work, but anti-stick features help.
Higher temps improve flow but require scorch control.
For EPDM: Choose a vacuum cold feed extruder with a long L/D screw (e.g., 18:1).
For Butyl Rubber: Opt for a low-compression screw (1.5:1) with temperature-controlled zones.
For NR: Standard cold feed extruder works, but a grooved feed zone improves output.

In which industries is rubber cold feed mainly used?
Rubber cold feed extruders are widely used across industries where precise, efficient, and continuous rubber extrusion is required. Here’s a breakdown of the key industries and their applications:
Seals & Gaskets: EPDM for door/window seals, HVAC gaskets.
Hoses & Tubing: Silicone (MQ), NBR, or FKM for fuel, coolant, and air ducts.
Vibration Dampers: NR or IIR for engine mounts and bushings.
Tire Treads & Sidewalls: NR, SBR, and BR blends for cold feed extrusion.
Inner Liners: Butyl rubber (IIR) for air retention in tubeless tires.
Roofing Membranes: EPDM for waterproofing sheets.
Expansion Joints: CR or NBR for bridge/road seals.
Cable Insulation: EPDM or XLPE for fire-resistant cables.
Conveyor Belts: NR/SBR for mining and logistics.
Roller Coverings: PU or NBR for printing/packaging machinery.
Silicone Tubing: Biocompatible catheters, IV tubes.
Food Conveyor Belts: FDA-approved rubber compounds.
Seals & O-Rings: FKM/NBR for chemical/oil resistance.
Offshore Hoses: CR/CSM for saltwater/UV resistance.
Footwear: SBR/NR for shoe soles.
Sporting Goods: NR for bicycle grips, yoga mats.
✔ Energy Efficiency – No pre-heating required.
✔ Material Versatility – Handles synthetic (EPDM, NBR) and natural rubber.
✔ Precision – Better control for complex profiles (e.g., seals, hoses).
Industries avoiding cold feed: High-temperature vulcanizing (HTV) applications may prefer hot feed.
