REACH

/in /by
What is REACH ?

REACH is a new European Community Regulation on chemicals and their safe use (EC1907/2006). It deals with the Registration, Evaluation, Authorisation and Restriction of Chemical substances. The new law entered into force on 1 June 2007. The aim of REACH is to improve the protection of human health and the environment through the better and earlier identification of the intrinsic properties of chemical substances. At the same time, innovative capability and competitiveness of the EU chemicals industry should be enhanced. The benefits of the REACH system will come gradually, as more and more substances are phased into REACH.
RoHS Compliance (Restriction of Hazardous Substances)

RoHS Compliance(Restriction of Hazardous Substances) is the nickname given to the European Union’s directive 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment. RoHS is closely related to the European Union’s directive 2002/96/EC on waste electrical and electronic equipment (WEEE). Now is the time to determine the impact of RoHS on one’s business because the directive goes into effect on July 1, 2006.

ASTM D 2000 Standards

/in /by

ASTM D2000 was introduced to provide engineers with a classification system for commercially available rubber materials and to provide a simple designation method called the “Line call-out.” Although the title specifies automotive application it is not limited to only the automotive industry. In fact several industries benefit from this standard.

The most common material classification system used in rubber parts specification is probably “Standard Classification System for Rubber Products in Automotive Applications.” or ASTM D 2000. This system is designed to aid in the selection of practical rubber products for specific environments and provides a “line call-out” designation for the specification of elastomer seal materials.


How to read an ASTM D 2000/ SAE J200 Line Call-Out


Specification Revision

ASTM D2000-99 M 2 HK 7 14 A1-10, B38, C12, EF31, EO88, F15, Z1

This indicates the revision year of D2000 to which the line call-out makes reference.


Measurement Units

ASTM D2000-99 M 2 HK 7 08 A1-10, B38, C12, EF31, EO88, F15, Z1

If an M is present, metric units will be used for tensile strength, temperature, and tear strength (MPa, °C, and kN/m respectively). If no M is present, English units will be used (psi, °F, and ppi respectively).


Grade Number

ASTM D2000-99M2HK708A1-10, B38, C12, EF31, EO88, F15, Z1

Indicates the level of test requirements to which a material may be subjected. For example, Grade 1 shows that only basic properties are required, while Grades 2-9 require additional testing criteria such as low temperature brittleness or special heat aging tests. In our example, we will be looking at a fluorocarbon material that must meet some or all Grade 2 requirements. Note that Grade Numbers may not be relevant to all material Types and Classes.


Type and Class

ASTM D2000-99M2HK708A1-10, B38, C12, EF31, EO88, F15, Z1

“HK” – The first letter, “H”, is the designation for Type (resistance to heat aging) as shown in table 1. The second letter, “K”, is the designation for Class (resistance to swelling in oil) as shown in Table 2.



 Type Test Temperature
A 70°C (158°F)
B 100°C (212°F)
C 125°C (257°F)
D 150°C (302°F)
E 175°C (347°F)
F 200°C (392°F)
G 225°C (437°F)
H 250°C (482°F)
J 275°C (527°F)

Class Volume Swell, max
A no requirement
B 140%
C 120%
D 100%
E 80%
F 60%
G 40%
H 30%
J 20%
K 10%


Table 2, Tested for 70 hrs @ temperature from

table 1 in ASTM Oil No 3.

 

The table shown below are the most common polymers used for type and class. Classification System D 2000 SAE J200 Material Designation (Type and Class)

 

Type of Polymer most often used
AA Natural rubber, reclaimed rubber, SBR, butyl, EP polybutadiene, polyisoprene
AK Polysulfides
BA Ethylene propylene, high temperature SBR, butyl compounds
BC Chloroprene polymers (neoprene), cm
BE Chloroprene polymers (neoprene), cm
BF NBR polymers
BG NBR polymers, urethanes
BK NBR
CA Ethylene propylene
CE Chlorosulfinated polyethylene (Hypalon), cm
CH NBR polymers, epichlorohydrin polymer
DA Ethylene propylene polymers
DE CM, CSM
DF Polyacrylic (butyl-acrylate type)
DH Polyacrylic polymers, HNBR
EE AEM
EH ACM
EK FZ
FC Silicone (high strength)
FE Silicones
FK Fluorinated silicones
GE Silicones
HK Fluorinated elastomers (Vito, Fluorel, etc.)
KK Perfluoroelastomers

 

For each Type and Class, ASTM D 2000 includes a table giving all basic requirements, physical properties, and all suffix requirements.

 

Hardness (Durometer)
This number indicates durometer range in Shore A units (plus or minus 5 points). In our example, the material specified would possess a hardness of 70±5 durometer.
Tensile Strength
The next two digits indicate the material’s minimum tensile strength. If measurements are in metric units, the digits show MPa. If measurements are in English units, the digits show psi and only the first two digits of that measurement are indicated. In our example (which is in metric units), the two tensile strength digits are “14” thus the minimum tensile strength required would be 14MPa. If this example were non-metric, this callout would be 20 (14 Mpa = 2031 psi).

The first six characters of a Line Call-Out give a lot of basic information about the type of elastomer required and its physical properties. Most specifications require more information to guarantee that the seal will meet the needs of the application.
Additional Requirement Suffixes
Suffixes appended to the Line Call-Out are letter and number combinations that indicate a material’s test and performance criteria per the Grade number indicated. In our example, A1-10 indicates a heat resistance test. B38 indicates a compression set test. C12 indicates resistance to ozone. EF31 and EO88 indicate fluid resistance criteria. F15 indicates low temperature brittleness criteria. Z1 indicates a user-defined requiremen, t as must be specified including test criteria. Refer to ASTM D 2000 for expanded suffix call-out details.
Suffix Letter Test Required
A Heat Resistance
B Compression Set
C Ozone or Weather Resistance
D Compression-Deflection Resistance
EA Fluid Resistance (Aqueous)
EF Fluid Resistance (Fuels)
EO Fluid Resistance (Oils and Lubricants)
F Low Temperature Resistance
G Tear Resistance
H Flex Resistance
J Abrasion Resistance
K Adhesion
M Flammability Resistance
N Impact Resistance
P Staining Resistance
R Resilience
Z Any Special Requirement (Specified in Detail)

Flocking

/in /by

Friction Reduction, Aesthetics & Insulating Value

Flocking is a velour-textured material that can be dyed to match virtually any color, and nearly any material can be flocked, making it easy to expand your product line.

Flocked surfaces help reduce friction, water absorption, vibration dampening, and are good thermal insulators.

The process is used extensively in many industrial applications, including: car windows, weather stripping and more.

RMA Standards for Cross Sectional Tolerance Table — Rubber Extrusions

The closer tolerance classes outlined below should not be specified unless required to do so by the final application and they should be restricted to the critical dimensions. The closer tolerances demanded, the tighter the control must be exercised when the material is being extruded and hence the higher the cost incurred.
