To be classified broadly as a TPE, a material must satisfy two fundamental criteria: (1) rubber-like elasticity and (2) thermoplastic processability (melt-processable and recyclable). To better understand this diverse family, thermoplastic …
Although both TPE (Thermoplastic Elastomer) and TPU (Thermoplastic Polyurethane) belong to the category of thermoplastic elastomers—meaning they combine the elasticity of rubber with the processability of plastics—they have distinct …
Fragrance Oils vs. Essential Oils comes down to one main difference. Fragrance oils are synthetic or nature-identical blends. Essential oils are natural plant extracts. Both work in perfume, but they act differently in four key areas: scent …
What separates a reliable fragrance oil supplier from a risky one? The answer rarely lies in a single price quote. It shows up in batch-to-batch consistency, complete safety documentation, honest cost structures, and dependable lead times. …
1. What Is SEBS? Styrene-Ethylene-Butylene-Styrene (SEBS) is a block copolymer produced by reacting Styrene-Butadiene-Styrene (SBS) with hydrogen. Specifically, it is a linear or star-shaped triblock copolymer composed of styrene as the …
Styrene Ethylene Butylene Styrene (SEBS) block copolymers are among the most versatile thermoplastic elastomers (TPEs) on the market. Produced by the selective hydrogenation of Styrene-Butadiene-Styrene (SBS), SEBS uniquely combines the …
HMDA epoxy curing agent 1,6-hexanediamine (CAS 124-09-4) is an aliphatic diamine hardener sold at 99.90% minimum purity with water below 0.05%. Its calculated amine hydrogen equivalent weight is 29.1 g/eq, and so the stoichiometric demand …
Liquid phenolic epoxy resin YLEP-631 is a PNE-type novolac grade with 2.7 epoxy groups per molecule. Its published window is an EEW of 168-180 g/eq, a viscosity of 1100-1700 mPa·s at 52 °C and hydrolyzable chlorine below 500 ppm. Seven …
3,4-Methyl hexahydrophthalic anhydride (MHHPA, CAS 25550-51-0) is a colorless liquid anhydride hardener of 50-80 cps at 25 °C. Assay is 98% minimum, the freezing point sits at or below -15 °C. Dosed at 110 phr in a 130 g/eq alicyclic epoxy, …
PACM epoxy curing agent is a colourless alicyclic diamine, 4,4'-diaminodicyclohexyl methane (CAS 1761-71-3), sold at 50-80 mPa·s and APHA 30 or below. Four amine hydrogens on a 210.36 g/mol molecule give a calculated AHEW of 52.6 g/eq, …
