Guangzhou Best Rubber & Plastic has been focusing on the customization and precision processing of PPSU (Polyphenylsulfone) products for many years. We have deeply explored the customization needs of high-end industries such as medical and food, and accurately grasped the core advantages of PPSU: medical grade, high temperature resistance and sterilization resistance. Using high-quality imported PPSU raw materials (meeting FDA, ISO13485 medical standards), combined with advanced injection molding and CNC precision processing technology, we can custom-make various non-standard PPSU precision components according to the drawings (CAD, STP format is preferred), samples or specific working condition requirements provided by customers. The tolerance can be accurately controlled within ±0.01mm, the surface is smooth and burr-free, and the batch consistency is strong. It can fully meet the harsh hygiene requirements of medical and food industries, and adapt to complex working conditions such as high temperature and chemical corrosion.

As a core product of medical-grade special engineering plastics, PPSU has been widely used in medical, food and other industries with extremely high requirements for hygiene and high temperature resistance. The following are specific customization cases :

Case 1: Medical Industry - Medical Instrument Housings, Sterilization Boxes: Customized PPSU medical instrument housings (such as endoscope housings, ultrasound equipment housings) and sterilization boxes for medical equipment manufacturers. Taking advantage of PPSU's excellent sterilization resistance, it can withstand various sterilization methods such as high-pressure steam and ethylene oxide repeatedly without deformation or performance attenuation. At the same time, it has good electrical insulation and impact resistance, protecting internal precision components, meeting medical-grade hygiene standards, and has been applied in batches to many hospitals and medical equipment enterprises.

Case 2: Medical Industry - Baby Bottles, Medical Infusion Accessories: Customized food-grade and medical-grade PPSU baby bottle bodies and medical infusion accessories (such as infusion tube connectors, syringe accessories). Using odorless and non-precipitating PPSU raw materials, it can withstand high temperature of 180℃, can be disinfected at high temperature repeatedly, safe and non-toxic, adapting to baby feeding and medical infusion scenarios, solving the pain points of traditional plastic bottles that are easy to age and have peculiar smell, winning high recognition from maternal and child and medical industry customers.

Case 3: Food Industry - Food Processing Equipment Accessories, High Temperature Containers: Customized PPSU food processing equipment accessories (such as food-grade valves, pipelines, stirrer blades) and high-temperature containers for food processing enterprises. Relying on PPSU's characteristics of high temperature resistance, chemical corrosion resistance and no precipitation, it adapts to high temperature and acid-base cleaning scenarios in food processing, ensuring food hygiene and safety. At the same time, it has the advantages of wear resistance and easy cleaning, adapting to various food processing equipment, meeting FDA standards for the food industry.

Case 4: Electronic Industry - High-End Electronic Equipment Housings, Insulation Accessories: Customized PPSU electronic equipment housings and insulation accessories for high-end electronic enterprises. Using PPSU's excellent electrical insulation and high temperature resistance, it adapts to the high-temperature operating environment inside electronic equipment, preventing short circuits. At the same time, it has impact resistance and aging resistance, extending the service life of electronic equipment, adapting to high-end sensors, precision instruments and other electronic equipment.

Case 5: Aerospace Industry - Precision Insulation Parts for Aerospace Equipment: Customized PPSU precision insulation parts for the aerospace field. Relying on its excellent high temperature resistance, radiation resistance and electrical insulation, it adapts to the extreme high temperature and radiation environment of aerospace equipment, ensuring stable operation of the equipment. At the same time, it has the advantage of light weight, reducing the weight of aerospace equipment, adapting to various aerospace precision equipment.
