ASTM D 707 for CAB Compounds

These rules are for ASTM D 707 standard classification systems for thermoplastic compounds made of plasticized cellulose acetate butyrate that can be pushed through a die or injected into a mold. These compounds have a butyryl content of less than 38 % and an acetyl content of less than 15 % and can contain dyes and pigments.

Overview

ASTM D 707 testing is a standardized material specification and test method for cellulose acetate butyrate (CAB) compounds to assess the physical, mechanical, and thermal properties of CAB molding and extrusion compounds used in various automotive, optical, industrial, and consumer product applications. ASTM D 707 specifies the material requirements, test methods, and classification standards to ensure that CAB compounds are validated to meet minimum standards for material qualification, inspection, and validation.

Scope, Applications, and Benefits

Scope

ASTM D 707 classifies and evaluates CAB compounds on the basis of certain physical and mechanical properties such as flow rate, tensile strength, flexural properties, impact resistance, and thermal properties. This allows material suppliers, material processors, and users to check compound properties against the requirements of ASTM D 707 classification and acceptance criteria.

ASTM D 707 testing evaluates:

Melt flow rate and processing characteristics of CAB molding and extrusion compounds
Tensile strength, elongation, and mechanical performance of CAB material specimens
Flexural strength and modulus of CAB compounds under defined loading conditions
Impact resistance and notched Izod performance of CAB molding compounds
Thermal and physical property compliance against ASTM D 707 classification requirements

Applications

Automotive trim, knobs, handles, and decorative interior components
Optical frames, eyewear, and transparent optical component applications
Industrial tool handles, instrument housings, and protective covers
Consumer product components requiring CAB compound material qualification
Material suppliers and compounders requiring ASTM D 707 product certification

Benefits

Supports ASTM D 707 material qualification and product specification compliance
Provides certified physical and mechanical test data for material supply agreements
Identifies CAB compound property deficiencies before production processing
Delivers traceable test documentation aligned with ASTM D 707 classification requirements
Reduces production risk by verifying compound performance early in the qualification cycle

Frequently Asked Questions

ASTM D707 tests cellulose acetate butyrate compounds by looking at certain properties, like viscosity or flow behaviour. This helps manufacturers make sure that the material is consistent and can be used in coatings, plastics, and speciality formulations.

ASTM D707 helps figure out if CAB compounds meet quality and performance standards during production. This makes sure that materials keep their proper processing properties, stability, and functionality in coatings, inks, and plastic formulations.

CAB compounds tested with ASTM D707 are often used in coatings, automotive finishes, printing inks, adhesives, and speciality plastics where consistent viscosity and processing properties are needed for the product to work well.

To see if materials meet certain quality standards, ASTM D707 testing involves making CAB compound samples in a controlled environment and measuring their physical or chemical properties according to set rules.

ASTM D707 tests certain properties of CAB compounds in a lab setting. It may not show how well they work in finished products, where things like exposure to the environment, formulation additives, and processing conditions can change how they behave.
