Acid-alkali storage tank fittings
Material advantages: PPpro™ is resistant to strong acids and alkalis; it does not corrode or deform even when exposed to hydrochloric acid, sulfuric acid, and sodium hydroxide solutions over a long period of time.
Print value: Traditional connectors require molding and injection molding, which is time-consuming and expensive. 3D printing enables customization on demand, rapid delivery of small batches of multiple varieties, and printing on the same day for emergency repairs, significantly shortening equipment downtime.

Electroplating hanging fixture clamps
Material advantages: PPpro™ is resistant to electroplating (chromium acid, cyanide, etc.), and PP itself is non-conductive, providing natural insulation.
Print value: Electroplating fixtures are complex in shape and have a wide variety of specifications. Traditional machining methods are costly. 3D printing allows for flexible customization of fixtures of different sizes and shapes to accommodate a wide range of products, reducing the cost of stocking tooling fixtures.

Laboratory ventilation duct components
Material advantages: PPpro™ is resistant to acid, alkali, and volatile gases (such as nitric acid and hydrochloric acid vapor); it does not become brittle or powdery over time.
Print value: Laboratory ventilation duct specifications are varied and quantities are small, making mold-making uneconomical. 3D printing allows for on-demand production, quickly meeting non-standard size requirements while the PP surface is smooth and easy to clean, meeting the requirements for clean laboratories.

Chemical pump body impeller
Material advantages: PPpro™ is chemically resistant and has low density (0.9g/cm³). Its leaf rotation inertia is small, providing faster response.
Print value: The leaf wheel shape is complex, making traditional CNC machining difficult and expensive. 3D printing enables one-piece molding without the need for assembly, and allows for rapid design iterations based on the working conditions, optimizing fluid efficiency.

Wastewater treatment aeration disc
Material advantages: PPpro™ is resistant to the acidic and alkaline components in sewage, and resistant to microbial attachment; it does not hydrolyze or degrade over long periods of immersion in water.
Print value: The distribution of aeration disc holes affects treatment efficiency. 3D printing can precisely control the hole size and distribution, enabling customized aeration solutions to improve wastewater treatment efficiency.

Chemical plant safety protection cover
Material advantages: PPpro™ resists chemical media spattering and weathering, and can be used outdoors and in acidic or alkaline environments for an extended period.
Print value: The equipment specifications on site vary, making traditional protective shields difficult to match perfectly. 3D printing allows for on-site measurement and rapid modeling and printing, enabling ”tailor-made” protective solutions that are highly customized and offer better protection.

Chemical Resistant Industrial Parts
Acidic/alkaline environment · Stable over long periods · Resistant to corrosion without failure
PP itself boasts excellent resistance to chemical corrosion, making it an ideal material for contact with acidic or alkaline media in industrial applications. However, traditional PP is difficult to 3D print, limiting the benefits of this technology. PPpro™ modifies the formulation to maintain PP’s inherent resistance to corrosion while allowing stable printing on desktop-grade FDM equipment. The printed parts can withstand exposure to corrosive media such as hydrochloric acid, sulfuric acid, sodium hydroxide, and chromic acid for extended periods without deformation, brittleness, or degradation. From chemical storage tank fittings to electroplating fixtures, from laboratory ventilation ducts to wastewater treatment components, PPpro™ makes on-demand manufacturing of chemical-resistant industrial parts truly possible.
