Chemical Resistance Guide 10

Product catalog summary

Introduction
The Chemical Resistance Guide is a detailed resource for assessing the compatibility of various materials with different chemicals, specifically for use with Xylem pumps. It is based on laboratory and field tests, as well as industry data. The guide advises that actual use should determine suitability, and it does not guarantee against chemical attacks on pump materials.

Rating System
The guide uses a rating system to evaluate material resistance:

A Rating: Little effect on material properties (Generally Satisfactory).
B Rating: Minor to moderate effect (Generally Satisfactory but should be tested).
C Rating: Significant change in properties (Generally Not Satisfactory, must be tested).
D Rating: Rapid deterioration or chemical attack (Not Satisfactory).

Materials without a rating should be tested.

Elastomer Properties
The guide details the resistance of various elastomers:

Buna-N: Excellent against petroleum-based fluids, vulnerable to ozone, ketones, esters.
EP/PP Blend (Santoprene): Resistant to solvents and chemicals, vulnerable to hydrocarbons.
EPDM: Excellent against ozone and chemicals, poor against petroleum-based fluids.
FFKM (Kalrez): Excellent chemical resistance.
FKM (Viton): Excellent oil and air resistance, vulnerable to ketones.
Fluoro-silicone: Moderate chemical resistance, vulnerable to brake fluids.
Natural Rubber: Excellent physical properties, poor against petroleum-based fluids.
Neoprene: Good weathering resistance, moderate against petroleum-based fluids.
Silicone: Excellent temperature properties, fair physical properties.

Gas Warning
Xylem pumps should not be used with gasoline or fluids with a flash point below 100°F (38°C).

Chemical Resistance Guide Tables
The tables rate various materials (plastics, elastomers, alloys) from A to D based on their resistance to specific chemicals, such as acids, alcohols, and hydrocarbons. These tables are crucial for selecting appropriate materials for specific chemical exposures.

Chemical Resistance Guide Overview
This guide evaluates the chemical resistance of materials like plastics, elastomers, and alloys, structured into tables categorizing their resistance to different chemicals.

Key Sections:

Materials Evaluated: Includes Polypropylene, Nylon, Polyethylene, Acetal Copolymer, Kynar, FKM, Buna, Silicone, EPDM, EP/PP blend, FFKM, 316 stainless steel, and Hastelloy.
Chemicals Assessed: Covers a wide range of chemicals, including acids, alcohols, oils, fuels, and industrial chemicals.
Resistance Ratings: Uses a grading system (A, B, C, D) to rate material resistance, with 'A' indicating high resistance and 'D' indicating low resistance.
Applications: Useful for selecting materials for manufacturing and industrial applications where chemical exposure is a concern.

Summary of Findings:

Plastics: Generally show good resistance to many chemicals, but performance varies with specific chemicals.
Elastomers: Exhibit varied resistance, often performing well against oils and some acids but less so against strong solvents.
Alloys: Metals like 316 stainless steel and Hastelloy offer excellent resistance to a wide range of chemicals, suitable for harsh environments.

Recommendations:
When selecting materials for chemical exposure, consider the specific chemical environment and consult the resistance ratings in this guide to ensure material compatibility and longevity.
