PP Ningbo Fude T30S
PP Ningbo Fude T30S Resin
Material Introduction: PP Ningbo Fude T30S is a highly versatile drawing‑grade homopolymer polypropylene, also widely used for injection molding. It delivers low melt flow rate, excellent toughness and favorable processability with broad application coverage.
Main Applications
Woven products: Traditional primary applications, including woven bags, tarpaulins, FIBC bulk bags, carpet backing, artificial turf, strapping ropes and packaging ropes. Good tensile strength and low elongation fit these working conditions well.
Daily‑use articles & general injection‑molded parts: For daily‑use goods, small containers and household articles such as buckets, basins, stools and toys.
Packaging materials: Besides woven bags, also applicable for film products such as tear‑film.
Modified‑material applications: Used as base resin for modification (filling, toughening, reinforcement). Suitable for high‑performance products including electrical accessories, auto components, mechanical parts, TV housings and recorder housings.

Processing Parameters
| Processing Item | Reference Range | Remarks & Instructions |
|---|---|---|
| Drying Treatment | Normally not required | PP water absorption:0.01%‑0.03%. Drying is unnecessary under proper storage. Dry at 80‑100 ℃ for 1‑2 h if material gets damp. |
| Barrel Temperature | 200‑280℃ | Melting point of homopolymer PP T30S:165‑170℃. Zone example: rear zone 160‑180℃；middle zone 180‑210℃；front zone 200‑230℃. Temperature can be moderately increased for thin‑wall or complex‑geometry parts. |
| Mold Temperature | 40‑90℃ | Recommended:50℃. Higher mold temperature improves surface gloss and dimensional stability yet increases cooling time and shrinkage rate. Lower mold temperature shortens cycle time but may cause poor surface appearance and warpage. |
| Injection Pressure | 70‑120 MPa | Adjust based on flow length, wall thickness and structural complexity. PP melt viscosity is sensitive to shear rate; raising injection pressure is usually more effective to improve flowability than raising temperature. |
| Holding Pressure | 30%‑60% of injection pressure | Sufficient holding pressure reduces shrinkage and sink marks. Avoid overly long holding time to prevent excessive internal stress. |
| Injection Speed | Medium‑high speed | High‑speed injection helps reduce internal stress, especially for thin‑wall articles. Reduce injection speed or raise melt temperature if surface defects such as gas marks appear. |
| Back Pressure | 0.5‑1.0 MPa | Moderate back‑pressure improves melt homogenization and venting, not mandatory. |
| Screw Speed | 50‑100 rpm | Avoid excessive screw speed to prevent shear‑induced overheating. |
