BIPB vs DCP for Crosslinking: Which Peroxide Fits Your EVA Foam, XLPE Cable and Rubber Line?
Dicumyl peroxide (DCP) and bis(tert-butylperoxy isopropyl)benzene (BIPB) dominate crosslinking of polyolefins and elastomers. Both release radicals that turn thermoplastics into thermosets, yet they differ in odor, dosage, processing window and cost. This guide helps EVA foam, XLPE cable and rubber processors choose the right grade - and know when switching pays off.

TGIC or HAA? A Practical Guide to Curing Systems for Outdoor Polyester Powder Coatings
Outdoor polyester powder coatings need a crosslinker, and the default for decades was TGIC - triglycidyl isocyanurate. Today formulators choose between TGIC and HAA (β-hydroxyalkylamide, the "TGIC-free" chemistry), a decision that shapes film performance, labelling and market access.

PFAS-Free Sand-Texture Additives: Keeping the Grain Without the Fluorine
PTFE micropowder has long been the hidden ingredient behind crisp sand-texture powder coatings: it stays solid while the resin melts, raising melt viscosity and scattering light into a uniform, low-gloss grain. That workhorse is now under regulatory pressure.

Low-Temperature Curing Powder Coatings: Formulating Below 160°C Without Sacrificing Performance
Most powder coatings cure at 180-200°C, which rules out MDF, engineered wood and many plastics and consumes energy on every metal part. Low-temperature curing, typically 120-150°C, opens new substrates and cuts cost - but it compresses the cure window, and the additives chosen decide whether the recipe works.

PPS Injection Molding Defects: Black Spots, Fiber Float and Warpage — Mechanisms and Fixes
Thanks to its excellent dimensional stability and flowability, PPS is widely used in precision injection-molded parts for the electronics and electrical industries. However, issues like black spots, discoloration, glass fiber blooming, and warpage or cracking are frequent. These defects not only compromise the appearance but also induce internal stresses, ultimately reducing the material's strength and service life.

Glass-Fiber-Reinforced Nylon (PA) Injection Molding: The 7 Defects and Their Root-Cause Fixes
Reinforced with glass fiber (GF), PA exhibits significantly enhanced strength, hardness, fatigue resistance, dimensional stability, and creep resistance. The dispersion of GF within the PA matrix and the interfacial bonding strength are crucial to its overall performance.
