PP EPS30R

>> PP EPS30R has a controlled density of 0.90–0.91 g/cm³

It is lightweight yet structurally stable, combining the benefits of plastic lightweighting with structural load-bearing capacity, thereby meeting the industry’s demand for lightweight yet high-strength products.

As a low-flow injection-molding grade, it maintains a stable standard melt flow rate of 1.0–3.0 g/10 min (230℃/2.16 kg). It exhibits moderate fluidity in the molten state and ensures stable molding, minimizing defects such as flash, shrinkage, and voids. It is particularly well-suited for the injection molding of thick-walled products and complex structural parts, resulting in high product yield rates.

>> Superior balance of rigidity and toughness, stable performance across temperatures

The primary advantage of EPS30R is its balance of rigidity and toughness, effectively overcoming the common issue of standard PP becoming brittle and cracking at low temperatures. It demonstrates excellent Izod impact strength at room temperature, and even at -20℃, the notched impact strength remains stable at ≥5 kJ/m², showcasing outstanding resistance to low-temperature impact and brittle fracture. Additionally, it offers a tensile yield strength of ≥21 MPa and balanced flexural modulus, ensuring finished products resist deformation and cracking. It withstands daily impacts, stacking pressure, and low-temperature environments, making it suitable for diverse applications such as outdoor use, warehousing, and cold chain logistics.

>> Excellent processing performance and broad molding adaptability

As an injection molding grade PP resin, EPS30R offers good thermal stability, a wide processing window, and high process tolerance. It enables stable molding for both standardized mass-produced items and complex, irregularly shaped parts, excelling particularly in the production of thick-walled products. It offers uniform post-molding shrinkage, high dimensional accuracy, and excellent surface finish, eliminating the need for complex post-processing; this effectively reduces production costs and boosts mass-production efficiency. Additionally, the raw material is low-VOC and odorless, meeting environmental standards for consumer and household products.

>> Weather-resistant, corrosion-resistant, and durable with a long service life

Like other polypropylene resins, it boasts excellent chemical stability, resisting acids, alkalis, common solvents, and is impervious to everyday chemicals and moisture. It also offers superior moisture resistance, rust resistance, and aging resistance. Performance degradation is minimal over long-term use. The finished products are wear resistant and impact resistant and do not easily age or become brittle, meeting rigorous requirements for long-term industrial reuse and outdoor storage.
