Polycarbonate[5]

Updated: 2026-09-25

Overview

Polycarbonate (PC) with a density of 1.30 g/cm³ is a versatile thermoplastic polymer known for its exceptional combination of properties. It is widely recognized for its high impact resistance, optical clarity, and thermal stability. The material's balanced density contributes to its strength-to-weight ratio, making it suitable for various industrial applications. First developed in the 1950s, polycarbonate has become one of the most important engineering plastics. Its 1.30 density variant offers particular advantages in applications where weight reduction is important without sacrificing mechanical performance. The material can be easily processed through injection molding, extrusion, or thermoforming techniques.

Physical and Chemical Properties

The 1.30 density polycarbonate exhibits several notable physical properties. Its light transmission can reach up to 90% of visible light, comparable to glass. The material maintains good mechanical properties across a temperature range from -40°C to +120°C, with a heat deflection temperature typically around 130-140°C. Chemically, this polycarbonate shows resistance to many aqueous solutions, aliphatic hydrocarbons, and alcohols. However, it can be attacked by strong bases, some acids, and certain solvents. The material's flammability rating is typically UL94 V-2, and it has a dielectric strength of about 15 kV/mm, making it suitable for electrical applications.

Main Applications

Polycarbonate with 1.30 density finds extensive use in automotive components such as headlamp lenses, instrument panels, and sunroofs. Its impact resistance meets stringent safety requirements while reducing vehicle weight. In electronics, it's used for smartphone casings, LED light covers, and electrical insulation parts. The construction industry utilizes this material for skylights, sound barriers, and safety glazing. Medical applications include surgical instruments, drug delivery systems, and non-breakable containers. Recent developments have expanded its use in 3D printing filaments and optical media production.

Safety and Storage

When handling polycarbonate with 1.30 density, standard industrial safety measures should be followed. Processing at high temperatures may release small amounts of bisphenol A, requiring adequate ventilation. Dust generated during machining operations should be controlled to prevent respiratory exposure. For storage, the material should be kept in its original packaging until use to prevent moisture absorption. Ideal storage conditions are below 30°C with relative humidity under 50%. Prolonged exposure to UV radiation should be avoided unless the material contains UV stabilizers. Bulk storage should maintain proper stacking to prevent deformation of pellets or sheets.

B2B Procurement Guide

When procuring 1.30 density polycarbonate, specify whether you need general-purpose or specialty grades. Key considerations include required certifications (ISO, FDA, UL), color requirements, and any needed additives like UV stabilizers or flame retardants. Lead times can vary from 2-8 weeks depending on quantity and specifications. Minimum order quantities typically start at 500 kg for standard grades. For consistent quality, establish relationships with reputable suppliers who can provide material traceability and technical support. Consider requesting samples for testing before large-scale purchases.
