1、Designation: D 5603 01 (Reapproved 2008)Standard Classification forRubber Compounding MaterialsRecycled VulcanizateParticulate Rubber1This standard is issued under the fixed designation D 5603; the number immediately following the designation indicates the year oforiginal adoption or, in the case of
2、 revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This classification covers the compounding materialcommercially known as recycled vulcanizate p
3、articulate rub-ber. Recycled vulcanizate particulate rubber is the product thatresults when vulcanizate rubber has been processed by somemeans to obtain a desired particle size distribution.1.2 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in
4、 thisstandard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2

Terminology3.1 Definitions:3.1.1 recycled vulcanizate particulate rubber,nrecyclable vulcanizate rubber that has been processed togive particulates or other forms of different shapes, sizes, andsize distributions.3.1.1.1 DiscussionThe words “vulcanizate” and “vulca-
9、nized” are interchangeable. Additional terminology associatedwith this classification can be found in Terminology D 1566.3.1.2 parent compound, noriginal compound used in theproduct.4. Significance and Use4.1 Recycled vulcanizate particulate rubber is important inrubber compounding. It allows the ru
10、bber compounder to adda certain percentage of rubber filler back into its parent orsimilar compounds or to use the material as substitute or standalone compound. Its use may lower compound costs orimprove performance characteristics, or both.1This classification is under the jurisdiction of Committe

Classification of Recycled Vulcanizate Particul
14、ateRubber5.1 Several grades of recycled vulcanizate particulate rub-ber exist. Their classification is based on two major character-istics: particle size distribution and the polymer type found inthe parent rubber from which the recycled vulcanizate particu-late rubber was derived.5.2 Particle Size
15、Distributionmaximum particle size. (Forproduct mesh size designations, see 5.5.)5.2.1 Coarse rubber powders are products with designationsof 425 m (40 mesh) or larger. These materials typically rangein particle sizes from 2000 m (10 mesh) to 425 m (40 mesh)regardless of polymer type or method of pro
16、cessing.5.2.2 Fine rubber powders are products with designationssmaller (finer) than 425 m (40 mesh). These materialstypically range in particle sizes from less than 300 m (50mesh) to less than 75 m (200 mesh) regardless of polymertype or method of processing.5.3 Classification by Parent Compounds:5
17、.3.1 Based on polymer/compound type alone, the threemost common grades (Grades 1, 2, and 3) used in rubbercompounding and three other grades are shown as follows:5.3.1.1 Grade 1Whole tire recycled vulcanizate particu-late rubber is prepared from passenger car, truck, and bus tiresfrom which the fibe
18、r and metal have been removed. The rubberis then processed to the desired particle size.5.3.1.2 Grade 2Car, truck, and bus tread recycled vulca-nizate particulate rubber is prepared from car, bus, and trucktread only, processed to the desired particle size. This materialis commonly referred to as “p
19、eel” rubber.5.3.1.3 Grade 3Tread recycled vulcanizate particulaterubber prepared by utilizing tire retread buffings only. Thismaterial is generated from car, truck, and bus tire retreadingwhere the processing (buffing) of the tire includes the tread andtire shoulder area only. This material is then
20、processed to thedesired particle sizes. The vulcanizate particulate rubber pro-duced from this material is usually characterized by someelongated rubber particles in the vulcanizate particulate rubberwith mesh size designations coarser than 600 m (30 mesh).When finer mesh sizes are produced, the elo
21、ngated nature ofthe particles is no longer present.5.3.1.4 Grade 4Whole tire recycled vulcanizate particu-late rubber prepared by utilizing tire retread buffings only. Thismaterial is generated from car, truck, and bus tire retreadingwhere the processing (buffing) of the tire includes the tread, tir
22、eshoulder area, and the sidewalls. This material is then pro-cessed to the desired particle sizes. The vulcanizate particulaterubber produced from this material is usually characterized byelongated rubber particles in the vulcanizate particulate rubberwith mesh size designation coarser than 600 m (3
23、0 mesh).When finer mesh sizes are produced, the elongated nature ofthe particles is no longer present.5.3.1.5 Grade 5Recycled vulcanizate particulate rubberprepared from off road tires, large equipment tires, industrialtires, forklift tires, farm implement tires, and others. This doesnot include car
24、, bus, and truck tires.5.3.1.6 Grade 6Recycled vulcanizate particulate rubbersare prepared from rubber vulcanizates from non-tire rubberproducts. This is not to imply that all polymer types can beused interchangeably. Actual classification according to poly-mer types shall be agreed upon between ven
