ABS/PMMA Sheets for Thermoforming
Our ABS/PMMA sheets are designed for thermoforming applications, with a typical forming temperature range of 130 to 140 °C. We strongly recommend using an aluminum mold for the thermoforming process.
Acrylic (PMMA) Capped ABS (Acrylonitrile Butadiene Styrene) is a co-extruded product that features a PMMA Capping Layer (5%) on a high-impact ABS base. This product is commonly referred to as PMMA/ABS Sheet.
Storage: If ABS/PMMA sheets are exposed to humid conditions for an extended period, it’s advisable to dry them before thermoforming. Ideal drying conditions involve temperatures of 80 degrees for approximately 2 hours, with an additional hour for every 1 mm of thickness. To ensure effective drying, leave 20 to 30 mm of space between sheets. For energy efficiency and reduced heating time, aim to minimize the time gap between drying and forming.
Chemical Characteristics:
Our ABS/PMMA plastic sheets are resistant to oil and water and can withstand typical environmental conditions, including exposure to acids, alkalis, light, and oxygen. However, the plastic is susceptible to dissolution in carboxylic acids, esters, intrinsic monomers, ketones, chlorinated compounds, and aromatic hydrocarbons.
Key Attributes:
The ABS/PMMA sheets exhibit high hardness, temperature resistance, and air resistance.
Surface Hardness: PMMA Capped ABS (also known as PMMA ABS or ABS PMMA) combines the essential properties of ABS (impact resistance, strength, and durability) with the benefits of PMMA (polymethyl methacrylate), resulting in outstanding scratch resistance and improved aesthetics. PMMA Capped ABS offers the advantages of ABS, a glossy finish, and an extended service life.
