Epoxy resin and hardener should be stored in a cool, dry place, tightly sealed in their original containers. Keep them away from direct sunlight, heat sources, and moisture, as these can affect their shelf life and performance. Storage temperature should ideally be between 60°F to 70°F (15°C to 21°C) to maintain their viscosity and prevent premature hardening. Avoid storing epoxy near chemicals or fumes that could contaminate it. Also, make sure the lids are clean and tightly closed after each use to prevent contamination and ensure that no air gets trapped inside, which might cause the epoxy to cure in the container.
PVC, or Polyvinyl Chloride, is a widely used thermoplastic known for its durability, chemical resistance, and versatility. Its mechanical properties vary with the type of PVC, whether rigid or flexible, and its formulation. Generally, PVC has a high tensile strength of about 50-70 MPa, making it resistant to physical impacts and pressure. Its elongation at break usually ranges from 20% to 40%, indicating moderate flexibility, especially in its plasticized forms. The material also has a good modulus of elasticity, typically around 2.4 GPa for rigid PVC, which contributes to its stiffness. Additionally, PVC exhibits a low thermal conductivity, making it an excellent insulator. The material's properties can be further modified with additives for specific applications, enhancing its UV resistance, fire resistance, or flexibility. Understanding these properties allows engineers and designers to select the right type of PVC for various applications, ensuring performance and longevity.
