Direct supply from Shandong Pulisi Chemical (Stock Code: 307785). Guaranteed purity, high-grade polymer compliance, and global logistics reliability.
The industrial landscape for hybrid copolymer tubes, specifically blending Ethylene Vinyl Acetate (EVA) and Polypropylene (PP), has witnessed exponential growth due to the rising demand for flexible, chemical-resistant, and high-purity fluid transmission paths. EVA/PP polymer composite tubing combines the crack-resistant properties and flexibility of EVA with the high thermal limits and structural stability of Polypropylene.
In modern industrial applications, these hybrid tubes are highly favored in medical fluid pathways, automotive fuel venting, industrial solvent conveying, and chemical dosing systems. Unlike traditional PVC, which requires phthalate plasticizers that risk leaching into fluids, co-extruded EVA/PP tubes offer an environmentally inert solution with superior flex fatigue resistance.
Globally, the market is driven by strict environmental directives like EU REACH, German BV, and US FDA requirements. Major industrial regions, including North America, Western Europe, and East Asia, are aggressively migrating their chemical process lines to hybrid thermoplastic elastomer (TPE) setups to meet zero-leaching specifications.

Understanding structural properties is critical to ensuring chemical compatibility, pressure thresholds, and long-term durability in your operations.
| Material Property | Ethylene Vinyl Acetate (EVA) | Polypropylene (PP) | Co-Extruded Hybrid EVA/PP Tubing |
|---|---|---|---|
| Shore Hardness Range | 70A - 90A (Highly Flexible) | 70D - 85D (Rigid / Semi-Rigid) | Customizable (Typically 85A - 50D) |
| Operating Temperature | -50°C to +60°C | 0°C to +100°C | -40°C to +85°C |
| Flexural Fatigue Life | Excellent | Good (Subject to stress-cracking) | Outstanding (Synergistic properties) |
| Chemical Resistance | Good for weak acids, alcohols | Superior for solvents, strong bases | Comprehensive (Dual-barrier layer) |
| Leaching Risk | Extremely Low (Phthalate-free) | Zero Leaching | Optimized for Food & Pharmaceutical Grades |
Note: The properties of hybrid EVA/PP tubes vary based on the vinyl acetate (VA) content (ranging from 9% to 28%) and the specific co-extrusion technology used in the manufacturing lines.

The global industrial plastics sector is shifting towards safety and environmental circularity. Over the next five years, key market drivers include:
Fluctuating petrochemical indexes make budgeting difficult for international buyers. Shandong Pulisi provides index-linked pricing and long-term supply agreements to guarantee supply stability and predictability.
We work directly with chemical logistics providers to ensure shipping spaces are booked well in advance, minimizing transit delays.
High-grade raw materials formulated to meet strict global production standards.
Serving industrial, mining, agricultural, and specialized chemical fields worldwide.
We connect with global partners to showcase our research, developments, and supply solutions.
Key considerations for design engineers and purchasing professionals to optimize value.
Higher Vinyl Acetate (VA) content increases flexibility, transparency, and impact strength, but reduces the melting temperature and overall pressure rating of the tubing.
For automatic chemical processing lines, wall thickness and outer diameter tolerances must be tightly controlled (within ±0.05 mm) to avoid leaks at barb fittings.
Verify that products comply with FDA, REACH, or FAMI-QS standards based on your target market requirements to avoid customs and regulatory issues.
