A PP welding rod is a thermoplastic consumable specifically designed for hot air, extrusion, or chemical welding of polypropylene (PP) plastics. Manufactured predominantly from high-grade PP resin, these rods are indispensable in industries where corrosive chemical resistance, durability, and ease of fabrication are vital.
The global PP welding rod market has exhibited strong growth, primarily driven by the booming chemical processing, water infrastructure upgrades, and environmental equipment sectors.
Property | Typical Value | Test Standard |
---|---|---|
Density | 0.91 g/cm³ | ISO 1183 |
Tensile Strength | 31 MPa | ISO 527 |
Elongation at Break | >150% | ISO 527 |
Melting Point | 165°C | ISO 11357 |

Our technical team assists with formulation tweaks, welding compatibility, and documentation (Material Certificates & RoHS/REACH) for your industry or region.
Only virgin-grade polypropylene homopolymer (PPH), copolymer (PPC/PPB), or customized reinforced grades are adopted. No recycled/inferior resins are allowed to maintain weld quality.
Standard diameters include 2, 3, 4, and 5 mm; Customization possible from 1.5 mm up to 8 mm. Lengths available as 1 m straight or in coil/spool formats. Tolerances: ±0.05 mm.
Follow ISO 21307 (welding procedures for thermoplastics) and DVS 2207-1. Surface preparation and hot air/extrusion welding must use certified welding equipment at 220–260°C.
Products comply with ISO9001:2015 quality management, RoHS/FDA tested where required. Each batch is accompanied by a test certificate: tensile, dimensions, and visual homogeneity.
Keep in a cool, UV-shaded, dry area, ideally 5–30°C. Avoid direct sunlight and strong oxidants for best shelf life (over 5 years).
Normal stock ships within 2–5 days; Custom orders (nonstandard size/color) require 7–15 days. OEM/ODM: allow extra 3–5 days for sample approval.
Welding compatibility guide, selection advice, physical/certification reports. Online & onsite support programs, including video technical assistance for critical projects.
Warranty: 12 months against manufacturing defects, 1:1 replacement or refund. Lifetime technical support for welding issues.
