Fiber Surface Treatment: Strength or Durability?
Two fiber surface treatment routes were compared on the same natural fiber and at the same dosage. One was an alkali route, the[…]
Silane Modified Nano Silica in WPU Films: The Test Data
Silane modified nano silica does not simply make waterborne polyurethane films stronger and more water resistant. In one loading study it pushed surface[…]
Wood plastic composite interface: routes and trade-offs
Wood plastic composites fail at the interface, not in the bulk. Polar wood fibers bond weakly to a nonpolar matrix, so stress transfers[…]
Filler Packing Density: The Lever for Composite Performance
Filler packing density, not total filler amount, limits how well a composite conducts heat and stress. The same filler can deliver roughly ten[…]
Polypropylene additives: loading ranges by process and job
Polypropylene additives exist because the polymer has gaps that no reactor can close. Antioxidants interrupt the oxidation chain that starts at the tertiary[…]
PLA filler interfacial adhesion without a compatibilizer
Poly(lactic acid) composites filled with wood flour and a thermoplastic starch were made with no compatibilizer at all, and the interfacial evidence was[…]
Coating crosslinking: the chemistry behind film performance
Coating crosslinking is the network of chemical and physical bonds that turns liquid resin into a solid, durable film. Strong covalent bonds build[…]
What Are Silicone Materials? A Complete Engineering Guide
Silicone materials are synthetic polymers built on an alternating silicon-oxygen backbone (Si-O-Si) with organic side groups attached to each silicon atom. This half-inorganic,[…]
5% KH550 Fly Ash Cenosphere Filled Polypropylene: Test Data
A fly ash cenosphere polypropylene composite reaches its best overall balance when the cenospheres are treated with the silane coupling agent KH550 and[…]
Ionic Silane Coupling Agents: How a Dynamic Ionic Network Fixes Weak Interfaces
An old line from Chinese philosophy says what is rigid breaks easily, while what is soft endures. Spend any time with filler modification[…]
