Polyurethane vs. Rubber: Choosing the Best Material for Performance

Passive Devices Passive devices are components that cannot modulate current using an external electrical signal. Classic examples include resistors, capacitors, inductors, transformers, and even diodes. Active Devices An active device can electrically control the flow of charge—essentially, it lets

Devoting an entire chapter in a modern electronics textbook to electron‑tube design and function may appear odd, given semiconductor dominance. Yet, beyond historical interest, tubes remain indispensable in niche domains where they outperform any solid‑state device yet invented. In certain high‑powe

Thermoset polyurethanes are very tough and durable materials. Due to their properties, it is important that special care is taken when machining them. Polyurethanes harder than 70 Shore A can be machined using processes commonly used for machining metals. Polyurethanes softer than 80 Shore A tend t

Due to their chemical compositions, most elastomers, including rubbers, polyurethanes, and silicones, are natural insulators. Electrical conductivity can be improved in these materials by including conductive additives in the material’s manufacturing process. In the case of polyurethanes, using con
