As of early 2026, a kilogram of HDPE and a kilogram of polypropylene quote within roughly 10-20% of each other, both stamped “chemically resistant” on the quote. So the part gets sourced on price. I’ve watched that one decision crack…
BASF’s current datasheet for PA66 with 25% glass fiber prints two numbers for every mechanical property: a dry-as-molded column and a conditioned column. Tensile modulus reads 8600 MPa dry and 6500 MPa once the part equilibrates to ambient humidity. The…
A snap-fit dispenser lid, a solvent-contact bin, and a painted housing are three different material decisions, and only one goes to ABS. The reputation that ABS is the better engineering plastic holds up right until a part has to flex…
A polypropylene data sheet usually carries four temperatures — a melt point near 165°C, an HDT near 85°C, a Vicat near 100°C, and a continuous-use figure near 90°C. To a buyer scanning the COA, they all read like “the heat…
Polypropylene is a plastic — one specific thermoplastic in the polyolefin family, not an alternative to plastic the way the question often gets asked. “Plastic” is the parent category that also covers polyethylene (PE), PVC, PET, and polystyrene (PS). So…
2-Ethylhexanoic Acid (2-EHA, CAS No. 149-57-5) is one of the most important branched-chain carboxylic acids in the specialty chemical industry, used to produce metal carboxylates, coating driers, synthetic lubricant esters, PVC stabilizers, hydroprocessing catalyst precursors, and pharmaceutical intermediates. Global supply…
Both polyethylene and polypropylene land in your warehouse as off-white pellets with a density near 0.91 and a single MFI on the COA. The pellets tell you almost nothing about which one belongs in your part. A converter choosing between…
2-Ethylhexanoic Acid (2-EHA, CAS No. 149-57-5) is one of the most widely used branched-chain carboxylic acids in the chemical industry. It serves as an essential raw material for manufacturing metal carboxylates, lubricant additives, coating driers, PVC stabilizers, catalyst precursors, and…
# Introduction 2-Ethylhexanoic Acid (2-EHA, CAS No. 149-57-5) is an important industrial carboxylic acid widely used in metal carboxylates, coating driers, lubricant esters, PVC stabilizers, catalysts, and specialty chemicals. As demand for high-performance additives continues to grow, efficient and sustainable…
Copolymer polypropylene resists dimethylformamide (DMF) at room temperature, and DMF does not dissolve it under any ordinary condition. Every chemical-resistance chart converges on the same cell: PP rates “resistant” to DMF at 20 °C, with negligible absorption on a one-month…
