(Polypropylene) Specific gravity: 0.9-0.91 g/cm3 Mold shrinkage: 1.0-2.5% Molding temperature: 160-220℃ Material performance Low density, strength and rigidity, hardness and heat resistance are better than low-pressure polyethylene, and can be used at about 100 degrees. It has good electrical properties and high-frequency insulation. It is not affected by humidity, but it becomes brittle at low…

(Polyoxymethylene) Specific gravity: 1.41-1.43 g/cm3 Mold shrinkage: 1.2-3.0% Molding temperature: 170-200℃ Drying conditions: 80-90℃ 2 hours Material performance It has good overall performance, high strength and rigidity, good wear resistance, low water absorption, good dimensional stability, but poor thermal stability, easy to burn, and easy to age when exposed to the atmosphere. Suitable for making…

(Polystyrene) Specific gravity: 1.05 g/cm3 Mold shrinkage: 0.6-0.8% Molding temperature: 170-250℃ Material performance Excellent electrical insulation (especially high-frequency insulation), colorless and transparent, light transmittance second only to plexiglass, coloring, water resistance, and good chemical stability. The strength is moderate, but the quality is brittle, and it is easy to cause stress brittleness. Resistant to benzene,…

Parameters: Material name: ABS Printing temperature: 220-240° Material density: 1.04±0.2g/cm3 Water absorption: 1% Tensile strength: ≥43MPa Elongation at break: ≥10.0% Bubble: no bubbles Characteristic: 1: High strength-stronger than PLA, impact resistance, heat resistance, chemical resistance, and difficult to degrade, more suitable for manufacturing 2: High precision-the wire diameter tolerance is controlled within 0.02mm, which is…

High Density Polyethylene (HDPE for short) is a non-polar thermoplastic resin with high crystallinity. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial or chemical preservation properties, and will produce chemical and acid resistant fermentation products….

From cookware to aerospace engineering, the applications and classification of Teflon have no bounds. It is well known for its strength, excellent temperature resistance, and non-sticky nature. However, this material is more complex than it may sound.   The Teflon coatings are also very useful in protecting the material from stickiness. Different types of Teflon…
