Fabric Over foam

Product catalog summary
Overview: The document provides detailed technical specifications and options for fabric over foam gaskets, which are used for electromagnetic shielding. These gaskets are made by applying metallized fabric to extruded foam, offering flexibility, lightness, and good shielding effectiveness. The tests mentioned were conducted under laboratory conditions, which may not reflect actual working conditions.
Specifications: The metallized fabric is typically made from nylon or polyester with a conductive varnish for protection. The document lists various types of foams, including PU foam (UL94-HB, UL94-V0, and others) and silicone foam, with their respective compression load deflection values at different percentages. The temperature range for these materials varies, with foam silicone release ranging from -40°C to +125°C and foam microcellular PU from 40°C to +90°C.
Applications and Advantages: These gaskets are suitable for input/output ports, data processing, telecommunications, and 19" systems. They offer advantages such as flexibility, multiple contact points, non-abrasiveness, and cost-effectiveness. Options include cutting to required dimensions.
Performance Metrics: Shielding effectiveness is measured at various frequencies (20MHz, 200MHz, 500MHz, 1GHz) with values provided for different fabric types. Surface resistivity and abrasion resistance are also specified, along with compliance with RoHS standards.
Profile Dimensions: The document includes extensive tables listing part numbers, dimensions (height, width, adhesive width), and types of profiles (rectangular, square, D, P, C, knife-edge, and profiles with clips). Each profile type has specific dimensions and adhesive width options.
EPDM Profiles: EPDM profiles covered with metallized fabric are detailed, with options for complete or partial fabric coverage. These profiles achieve a sealing level of IP55 according to IEC529 tests.
Sub-D Joints: Specifications for Sub-D joints (9pts, 15pts, 25pts, 37pts, 50pts) are provided, with part numbers and dimensions.
Tolerances: Tolerances for standard lengths are specified, ranging from ±0.38mm to ±1.50mm depending on the length.
Part Numbering System: The document explains the part numbering system, including options for foam type, fabric type, and adhesive options. Specific codes are used to denote different materials and configurations.

Fabric Over foam-2

Metallised fabric is made from nylon or polyester and covered with a fine metallization. To ensure good mechanical strength and high corrosion resistance, the metallization is protected by a conductive varnish. The fabric is then applied to extruded foam. Gaskets made in this way offer flexibility, lightness and good shielding effectiveness Examples of applications: - Input/Output port (I/O) - Data processing - Broadcast, Telecommunications - 19" system - Front panel, plug-in module Advantages: - Flexible - Multitude of contact points - Nonabrasive - Economical - Cutting to required dimensions...

EPDM profiles covered with metallised fabric Part number The use of these gaskets makes it possible to achieve a sealing level= IP55 (according to test IEC529) * The fabric only covers half the EPDM gasket. This solution has the advantage of insulating the conducting part of the exterior environment, thus protecting it against corrosion. The conductive fabric can cover the profile from above or from below the profile (7G6 and 7G8 profile only) Cover from above Cover from below These tests were carried out in laboratory conditions which are not representative of working conditions.
