How to prevent stress cracking
What is stress cracking? When force is applied to plastic, it travels along the polymer chains causing molecules to strain to remain in contact. The polymer chains eventually creep toward the pull and deform. This stage is called creep. With force and time, crazing or stress cracking occurs. Adding chemicals or temperature can speed … Continue reading “How to prevent stress cracking”

Adhesives for Die Attach for electronics
Adhesives offer a convenient method of attaching electronic dies, semiconductors or silicon wafers to electronic circuitry. Key properties which make adhesives attractive for this type of application include: -Thermal management – adhesive can transfer and dissipate heat effectively, thermally conductive adhesive are desirable -Electronically insulative with high dielectric strength – this helps prevent transfer of … Continue reading “Adhesives for Die Attach for electronics”
What is a food safe epoxy? Do they contain bisphenol A?
What is bisphenol A? Bisphenol A is an organic synthetic compound used in formulating plastics and epoxy resin. The chemical formula is (CH3)2C(C6H4OH)2. In order to formulate an epoxy adhesive, one must have either bisphenol A or bisphenol F. Bisphenol A (BPA) is generally preferred for its curing properties. What is a food safe epoxy? … Continue reading “What is a food safe epoxy? Do they contain bisphenol A?”
