Polystar supplies specimen collection nibs and pads, as well as vents, filters, barrier vents, shutoff filters, porous media, and other types of porous components for use in diagnostic applications. Made of materials that are non-cytotoxic and biocompatible, parts can be sterilized with steam, gamma irradiation, ethylene oxide (EtO), etc.

Polystar Technologies’ precision manufacturing capabilities make us a reliable source for porous life sciences and biotech solutions. We provide customized, exacting solutions for demanding filtration, venting, adsorption, absorption, sparging, or diffusing applications, including:

• Barrier Vents, valve filters and pump filters to prevent contamination while ensuring pressure and/or heat dissipation.
• Floating filters and pre-filters to enhance filtration efficiency in bioprocessing functions.
• Precision-molded spargers optimizing Oxygen Transfer Efficiency (OTE) in bioprocessing system.
• In-line filters and diffusers for blood transfusion, dialysis machines, and drug delivery systems.
• Absorbent nibs, sample pads and absorption pads.
• Shutoff or self-sealing filters to ensure that liquids do not damage sensitive system components.
• Multi-function filters which eliminate targeted particulates, ensure balanced pressure, and provide EMI protection.

Utilizing either medical or standard grade thermoplastics, porous parts from Polystar meet high-performance demands in a wide variety of biotech and life sciences applications. Polystar will work closely with your engineering team to deliver custom solutions for your next-generation product design.

Polystar Technologies’ frits, filters, barrier vents, shutoff filters, wicks, absorbers, adsorbers, and other porous components are used in scientific and laboratory applications. Made of sintered porous materials that are non-cytotoxic and biocompatible, parts can be sterilized with steam, gamma irradiation, ethylene oxide (EtO), etc.

Some of the solutions we supply include:

• Frits and filters with narrow pore size distributions for analytical instrumentation including dissolution and chromatography systems, as well as inline filters, pump inlet filters, and sampling filters.
• Precision frits and filter components for Solid Phase Extraction (SPE) cartridges and columns.
• High-performance filters and frits for pipette tips. These can be made either hydrophilic (for efficient sample uptake) or hydrophobic (for contamination and water ingress prevention).
• High-capacity porous wicks for chillers to aid in water evaporation. Chillers can be found in analytical instrumentation, lab equipment, MRI machines, CT scanners, blood cooling systems, and radiation therapy machines.

PolySmart™, our proprietary manufacturing process, ensures we achieve the desired pore size and porosity levels for superior and consistent performance. Polystar produces porous components for use in laboratories from PE, PTFE, PP, PES, PEEK, and other materials.

Electronic devices may be exposed to contaminants and variations in temperature, humidity, or pressure. Additionally, some electronics require protection from corrosive agents or Airborne Molecular Contamination (AMC). Any of these factors can lead to device failure. Below are some ways Polystar Technologies addresses these issues:

• Hydrophobic barrier vents from Polystar provide superior venting and device protection for sensors, monitors, analyzers, MEMs devices , and other types of microelectronic devices.
• Hydrophobic vent components provide IP66+ rated protection for electronic enclosures. Whether outdoor on electronic displays, telecommunications Outside Plant (OSP) enclosures , traffic signals and similar equipment, customized vents provide the protection needed for reliable operation in extreme environments.
• Barrier vents with adsorbent characteristics help equipment operate more reliably in sensitive chemical environments and meet NEMA requirements regarding corrosive agents.
• Certain enclosures require Electrostatic Discharge (ESD) protection. Polystar’s manufacturing process allows the customization of various ESD materials with polymeric materials. The result is a barrier vent or particulate filter with the ESD protection your application requires.

Polystar Technologies creates precise, customized solutions for the challenges of contamination and fluid control in industrial and energy environments. We will work with your engineering team to protect against the ingress of gas, liquid, or solid contaminants, to develop precision fluid delivery solutions, or to deliver, capture, contain, or neutralize targeted chemicals.

• Custom-designed porous components can be used in diffusive mixing, extraction processes , hydrogenation, or ozonation.
• Spargers aid in beverage carbonation, distillation, wastewater treatment, fermentation, and absorption.
• NEMA- or IP-rated hydrophobic barrier vents help prevent contaminants from damaging sense elements and microelectronics.
• Breathable, water resistant vents prevent contaminants from damaging cameras, lighting, surveillance equipment, monitors, and controls.
• Custom-designed aeration components enhance fine bubble aeration with high Oxygen Transfer Efficiency (OTE).
• Separators, vents, and flame arrestors enhance the safety and performance of batteries and fuel cells.

Polystar will help you in selecting the optimal material for your application, whether it’s a standard offering or a custom material.

Many consumer products, appliances, and devices require filtration, venting, diffusion, adsorption, or wicking capability. Polystar Technologies’ wide range of sintered porous media provide these types of functions, including:

• Wicking to dispense fragrances in a controlled fashion.
• Fluid delivery to supply creams, lotions, or other liquids.
• Adsorption to remove unpleasant odors.
• Barrier venting to prevent the ingress of contaminants while maintaining the flow of gases.
• Filtration to remove smoke, dust, or other contamination.
• Venting to dissipate heat or pressure generated by phones, tablets, laptops, cameras, printers, home appliances, tools, or other equipment.
• Integrated shielding to prevent Electromagnetic Interference (EMI).

Sintered porous plastic components allow manufacturers to meet NEMA or IP requirements. They enable manufacturers to ensure seal integrity, ensure electronics are dust tight, increase water resistance, or permit operation in harsh environments. Whether with a standard offering or a custom application, Polystar delivers solutions for your next-generation product design.

Sintered porous plastics from Polystar find use in venting, filtration, and diffusion within all types of applications, some of which are automotive. For example:

• Gas Sensors – Whether produced from virgin or impregnated material, sintered porous plastics play a crucial role in vehicular gas sensing as barrier vents.
• Mechanical Assemblies – Sintered porous components enhance lubrication, increase fluid filtration and cooling, reduce friction, dissipate heat, and aid in fluid management in axle systems, transmission systems, transfer cases or power transfer units.
• Tanks and Reservoirs – Porous plastics are used in brake fluid reservoir vents, fuel tank vents, hydraulic fluid reservoir vents, etc. They provide pressure equalization while preventing contaminants like dust and debris from entering fluid reservoirs.
• Headlamp Lighting – In order to prevent condensation and fogging, hydrophobic, porous plastic vents with desiccating features help control airflow while hindering moisture buildup.
• Vehicle Batteries and Fuel Cells – Sintered porous plastics are used as separators, vents, and flame arresters.
