Welcome to ThermoPore's eCatalog! While the majority of ThermoPore's production originates with captive tooling, tooling that is used exclusively for one particular customer, the part geometries listed within this eCatalog originate from tooling that is enrolled in ThermoPore's newly created ToolShare™ program. Need information about a combination or would you like to order a sample for quick evaluation? ThermoPore makes the process as easy as 1-2-3. Just select a ToolShare™ geometry, select an X-Pore™ Material, and request information or submit your sample order by clicking the "Order Sample" tab below.

ThermoPore's X-Pore™ material listing also serves as an excellent starting point for your development project. ThermoPore's standard grades of bronze are presented in this convenient table for your study and use. The X-Pore™ materials listed within this table characterize ThermoPore's material capabilities in very general terms. Of course, ThermoPore possesses ample amounts of material processing capability that can considerably broaden this material offering, so don't limit your design to the material options shown here.

Description of Material Parameters

Pore Size

Pore Size is determined through Mercury Intrusion Porsimetry. Due to mercury's high surface energy, the porous plastic does not seek to be "wetted" by the mercury. Put another way, the mercury does not naturally enter to pores of the porous plastic (as water does with a typical kitchen sponge). A mercury intrusion porsimeter, however, applies a know amount of force onto the liquid mercury in order to infuse the mercury into the pores of the porous plastic. Generally speaking, it takes more force to push the mercury into pores of smaller diameter and the mercury intrusion porsimeter measures and records the applied force and the amount of mercury infused into the porous plastic's structure. Analytical analysis of the curve creates a pore size distribution that is "bell" shaped in nature. The pore size value listed above represents the average pore size - but there are often times pore +/- 20% of this size within the porous plastic in lesser and lesser quantity as you travel away from the average.

Pore Volume

Pore Volume is determined through Mercury Intrusion Porsimetry testing. During this test, the sample's exterior (or envelop) volume is measured. Next, the volumetric amount of mercury introduced into the sample is record. The pore volume of the porous plastic is expressed as the ratio of air volume to plastic volume as a percentage. Therefore, a pore volume of 45% would describe a porous plastic article that was 55% plastic, and 45% void of plastic.

Air Permeability

Air Permeability describes the resistance that air incurs as it attempts to travels through a porous material. Materials with tight pore structure usually create more resistance to air flow than materials with more open or larger pore sizes. Air Permeability is typically expressed with three parameters: air flow rate, differential pressure, and time. Because air permeability is not linear with different face velocities, the proper specification of air permeability should include both differential pressure and face velocity values. In one scenario, the differential pressure can be held constant and the face velocity can be recorded (3 ft/min @ ΔP of 1.2" H2O). In a second scenario, the face velocity can be held constant and the differential pressure can be recorded (ΔP of 2.6" H2O @ face velocity of 3 ft/min). In yet a third scenario a Gurley number can be referenced. The Gurley number is equal to the amount of time (seconds) required for a known volume of air (~100 cc) to pass through a known area (~ one-square-inch) of porous material when a constant pressure is applied to the influent air stream (Gurley number of 23 sec.).


Tool Share Geometries

Molded parts require tooling - there's simply no way around it and production tooling can be a costly proposition. But what if you approach ThermoPore early enough in the design process and your assembly embodies enough flexibility to accommodate a part made form existing ThermoPore tooling? Alternatively, have you ever wondered if your part design and subsequent production tool has potential applications in other non-competitive industries. If you answered "yes" to either question then keep reading.

Consider the recent development project whereby ThermoPore was asked to produce a single diameter, industrial, hydrophobic wick. The same part geometry just happened to meet the needs of a development engineer designing a perfume cosmetic applicator. So what did ThermoPore do? We built a bridge between these two seemingly unrelated and non-competitive project opportunities and enrolled the tool into ThermoPore's ToolShare™ program.

So what is the ToolShare™ program and how does it work? If you chose to enroll your production tool into ThermoPore's ToolShare™ program, you'll receive tooling at a substantially reduced cost AND the product made from this tool will be sold to you for exclusive use into your selected market application. Even more, ThermoPore will cover the tools maintenance and replacement cost for life of the part's enrollment. Mean while, ThermoPore will make available this tool available to customers use into markets that are non-competitive to your business interest. Leverage ThermoPore's ToolShare™ for you own benefit today!

While ThermoPore does maintain an inventory of items made from the ToolShare™ tooling geometries, we cannot guarantee that we'll have every material iteration in stock at the time of your order. In the event that ThermoPore finds it necessary to manufacture custom samples for your evaluation, a sales engineer will contact you to discuss pricing options.
