Ultraplen® PP — Base Modified Polypropylene Homopolymer

Description

Ultraplen® is the in-house PP compound line of Material Wizard: modified polypropylene compositions with improved rheology, an extended processing temperature window and an optimized stiffness/elasticity balance for injection molding and extrusion.

The base grade Ultraplen® PP (unfilled homopolymer) is presented in this card. It combines the high clarity of its spherulitic structure, a low density of 0.90 g/cm³ and resistance to deformation under flexural loading. It is used both as a stand-alone structural material and as the polymer matrix for specialized filled Ultraplen® grades.

Full Ultraplen® line (current catalog)

• Ultraplen® PP — base unfilled modified homopolymer (this card)
• Ultraplen® 530 — 30 % glass-filled (GF), a replacement for glass-filled PA in technical parts
• Ultraplen® PP GF30/4164 — 30 % glass-filled copolymer for pipe and engineering applications
• Ultraplen® PP LGF55 — 55 % long glass fiber masterbatch (let-down ratio up to 1:3)
• Ultraplen® PPMF40 — 40 % talc mineral-filled, increased stiffness and heat resistance
• Ultraplen® 600 — self-extinguishing PP with an FR package for electrical enclosures

Advantages

• High physical and mechanical performance at low density (~0.9 g/cm³ — lighter than water)
• Improved surface quality of molded parts: matte or glossy finish as required
• Rheologically optimized — no sink marks or warpage in thick-walled parts
• Good stiffness/elasticity balance — withstands impact loads without brittle failure
• Compatible with compatibilizers and fillers for further modification
• Low water absorption (<0.02 %) — dimensional stability in any climatic conditions
• Environmentally safe: complies with EU 10/2011 for food contact (no FR packages or plasticizers in the base formulation)

Limitations — honestly

• Lower heat resistance than PA or PPS — service range up to 100–110 °C (continuous)
• UV-unstable in the base formulation — outdoor applications require a UV-stabilized grade (HALS package)
• Sensitive to oxidation in long-term service above 90 °C without an antioxidant package
• Limited resistance to strong oxidizers, concentrated acids and aromatic hydrocarbons
• For structural stiffness above a 1.5 GPa modulus, use Ultraplen® 530 (GF30) or Ultraplen® PPMF40
• The base grade is rated HB per UL 94 — for V-0/V-2 choose Ultraplen® 600

Target applications

Packaging and containers: technical crates, buckets, logistics containers, IBC lids, thin-wall injection-molded packaging.

Home appliances: housing parts for washing machines and small kitchen appliances, fan and vacuum cleaner components.

Industry: dispensing systems (where water contact is permitted), cold-water supply fittings, technical covers and housings.

Automotive (interior): decorative trim, holders, cabin hardware components, vents for climate-control systems (NOT for under-hood applications — PA or PPS is used there).

Agriculture: irrigation system parts, greenhouse equipment components (with a UV additive).

Global counterparts

Parametrically comparable base PP homopolymers: LyondellBasell Moplen® HP500N / HP400V (injection molding), SABIC PP 575P, Borealis Borform™ HD120MO, TotalEnergies Lumicene® MR2002. Ultraplen® PP is offered as a localized alternative with flexible batch sizes (from 25 kg), flexible lead times and the option of tailoring to a specific application (MFR, color, UV/FR packages).
