Soft of Firm Soft of Firm Foams materials range from Ultra Soft to Firm. Softer foams require less pressure to compress and may be more conformable. Firmer foams may offer be better durability. This is a general description, please use the additional engineering filters below if looking for specific compression deflection or shore ratings. +

Density Density Density is the measurement of weight, usually measured as pounds per square foot (lb/ft³). This is the weight of the material if it was shaped into a 1 foot square cube. A common misconception in the foam tape industry is that density relates to softness, while this may be true for some materials it will vary based on the product make and material. Due to the nature of foam, many of our products have a weight range. +

Compression Deflection 25% Compression Deflection 25% Compression Deflection 25% is the force required to compress the foam 25% of it's original thickness. Softer foams will only require 2-5 psi to compress 25%. Firmer foams may required over 13 psi to compress 25%. Used as the third identifier in ASTM's D1056 classification. This softness test is preferred by Pres-On compared to shore/ durometer scales. +

Shore Durometer Shore Durometer Shore Durometer is a device for measuring hardness of materials. Typically foams are measured on the OO scale. The higher the number the firmer the material. Due to the nature of foam this should considered an approximate. Pres-On recommends using "Compression Deflection" over Durometer when determining the softness of foam. +

UL Rating UL Rating UL Rating products have been tested and inspected to meet the specific test standards developed by UL. There are various UL standards such as "UL 50" - Enclosures for Electrical Equipment, "UL 94" - Tests for Flammability of Plastic Materials for Parts, "UL 508" - Industrial Control Equipment, "UL 507" - Gasket and Seals, and more. Use this filter if you are looking for product that meets a specific UL rating. +

High Temperature Rating High Temperature Rating High Temperature (Service) is the high temp rating for continuous use. Many foams may be able to handle higher temperatures at intermediate, or short durations. If your application requires the foam to meet a high temperature please use this filter to sort our products by temperature rating. +

High Temperature Rating

Low Temperature Low Temperature Low Temperature (Service) is the low temperature rating of the foam for continuous or flexible use. Some materials may have a lower rating for static applications. Use this filter if your application requires the material to meet extreme low temperature ratings. +

Low Temperature Rating Low Temperature Rating Some materials are more brittle than others in cold environments. Use this filter if your application requires the material to meet extreme low temperature ratings. +

Low Temperature Rating

Surface Texture Surface Texture Smooth finish: flat surface without texture or a skin. Skin surface: a casted skin over the cell structure of the foam. Other textured surfaces such as criss-cross, embossed, ribbed are a unique feature to specific materials. +

ASTM D1056 Classification ASTM D1056 Classification ASTM D 1056 classification is used for rubber and synthetic rubber foams only. It denotes the Type, Class, Grade. Type: 1 = open cell, Type 2 = closed cell. Class A = non-oil resistance, Class B = oil resistance with low swell, Class C = Oil resistance with medium swell, Class D = extreme temperature resistance. Grade 1 = 2-5 psi 25% compression deflection (soft), Grade 2 = 5-9 psi 25% compression deflection (medium), Grade 3 = 9-13 psi 25% compression deflection (firm), Grade 4 = 13-17 psi 25% compression deflection (extra firm). +

Compression Set Compression Set Compression set is the % of material that does not rebound after the material has been under a prolonged compressed load. The lower the percentage the better the rebound. Sometimes referred to as C-Set. +

Tensile Strength Tensile Strength Tensile strength is the maximum stress the material can withstand when stretched before breaking. +

Enlongation Enlongation Elongation is the measurement of how long the material can be stretched before it breaks. +

Outdoor Rating Outdoor Rating This filters products that are suitable for outdoor environments. Note, a rating of excellent for outdoor does not mean the foam is recommended direct sunlight exposure, please use our UV exposure filter for applications in direct sunlight. +

UV Exposure UV Exposure UV exposure is how well the material performs with prolonged exposure to sunlight. Use this filter if your application requires the foam to be in direct exposure to sunlight. +

Flammability Rating Flammability Rating Various tests for flammability / burn resistance. FMVSS 302 is the Federal Motor Vehicle Safety Standard No. 302 for flammability of interior materials. Other UL and ASTM tests are listed. +

Type of Liner Type of Liner Compression Liner: Liner that uses the force of the cap to seal. Pressure Seal: Liner with a pressure sensitive adhesive that adheres to the neck of your bottle. Heat Induction Foil Seal: Non-contact heating process that hermetically seals a foil based liner to your bottle. 2-Piece Heat Induction Foil Seal: Single liner material that separates into two pieces during the heat induction process, a hermetically sealed foil liner to your bottle, and a reseal foam or pulp compression liner to retain in the cap. Vented Heat Induction Foil Seal: Liners designed to allow venting of internal pressure. +

Cap Size Cap Size Most cap sizes are noted with the "neck size-thread finish", example 38-400 fits a 38mm neck bottle with a one turn thread. The liners size is considered a nominal size, the actual size of the liner usually measures smaller than the nominal size, (example 38mm's actually size is 36.8mm). Size standards were created by Glass Packaging Institute (GPI) and Society of Plastics Industry (SPI). Our liners are made to fit the common "E" measurement (outside diameter of the bottle neck), and inside the cap's "T" measurement (outside diameter of the thread). We also have 100's of sizes for any custom or unique cap design. If your size is not listed please select "Custom". +

Bottle Material Bottle Material Knowing your bottle material is very important when selecting a heat induction liner. The sealing element of a liner is designed to specifically seal to different materials. Universal liners seal to most all bottle types, but for the best seal it's recommended to select a material designed for your bottle. Note: PE liners will not seal to PET bottles, and PET liners will not seal to PE or Glass. +

Product Product in Bottle Product Product in Bottle Liquids are recommended to be sealed with heat induction foil seals. Pressure seals and many vented liners are recommended for dry goods only. Chemically aggressive products may need a custom liner. +

Liner Thickness Liner Thickness For standard one-piece heat induction foil seals, .007" to .01". Most common pressure seals and PE foam liners use .020" thickness. Some specialty cap and bottles or two-piece heat induction liners require special thickness. +

Print Print Heat induction liners are commonly plain (no print). Pressure seals are commonly printed with "Sealed for your protection" (SFYP) in Red, or Black. Custom print is available for large minimum production runs. +

Cap Liner Insertion Service Cap Liner Insertion Service Pres-On offers automatic cap lining insertion services. Our industry leading insertion machine can line most common caps from 20mm to 120mm. Special sizes available with new tooling. +

Liner Removal Service Liner Removal Service Pres-On has a machine that can remove liners from most common caps. If you have a cap with the wrong liner, we can remove that liner and automatically insert the correct liner. +
