ANSWER: We do not recommend that anything other ‘A’ rated combinations are used. If you select a chemical to material rating of B the warranty is void. The pump may have serious problems and then again, there may be no problems.

Ask what materials are presently being used to transfer the fluid or if there is a manufacturer’s recommendation that is on the fluid container, etc. B. If there is no other information on this chemical, you will have to check with the manufacturer of the fluid and find out what is recommended.

Painted surfaces are likely at some time to come in contact with chemicals, which react with and thus adversely affect the characteristics of the painted product or its properties in use. The most common form of chemical attack is from acidic or alkaline media. E.g. certain resin systems in the paint industry are cured by a catalytic process set of by acidic conditions. The acidic reagents present must not affect pigments used in these systems.

Early in our evaluation of MatCon® performance, we consulted Dr. Henry Haxo, then President of Matrecon, Inc. about testing for chemical resistance. Using his previous experience in developing performance standards for geomembranes, we devised a testing program to evaluate the resistance of MatCon® to attack by leachate from municipal solid waste.

For information regarding the chemical resistance of Teflon® please see our Chemical Compatibility Data.

A PVC liner will survive exposure to a large variety of chemicals, even though the chemical could have some effects on the liner, without causing the liner to fail. If you have a specific concern, give us a call at 800-524-8672.

Koroguard GF and Chemguard GF offer the highest chemical resistance while other products offer moderate to low resistance. One need to know the PH value of the chemical or concentration of the chemical before selection of suitable product for the application.

It is the process of cleaning RO membranes with certain recommended chemicals to prevent the organic, inorganic and biological fouling of RO membranes.

There are two phenomenons which characterize a glove's resistance to contact with a given chemical: Degradation : deterioration of the glove, manifested by modification of physical properties (eg. softening, hardening). Permeation: a phenomenon which is characteristic of solvents which, depending on the type, may gradually penetrate the glove, sometimes with no visible signs of degradation. In order to help you choose the most appropriate gloves, Mapa offers a Chemical Resistance Index.

Like all precast, prestressed concrete products, hollowcore slabs have excellent fire resistance. Depending on thickness and strand cover, ratings up to a 4-hour endurance can be achieved. A fire rating is dependent on equivalent thickness for heat transmission, cover over the prestressing strand for strength in a high temperature condition and end restraint. Underwriters Laboratory (UL) publishes fire ratings for various assemblies.

The composite materials are highly water, wheater and chemicla resistant. This resistance is also the most influenced by type of used resin. A representative choice of chemicals is given in the table. A veil is added into the profiles under their surface. This veil protects within UV inhibitors degradation of materials.

Several of you have asked if you could include a note in the body of the email when rating the Chart of the Day. When you rate the Chart of the Day, your email software opens up with the address and subject fields already complete. From there you can simply click send or first write a brief note in the body of the email and then click send. Either way is fine by us.

Unfortunately, there is no simple answer to that question. The high heat resistance of modern thermoplastic materials has effectively eliminated ... read more

Our ratings of reviews are specific to product category, time and purpose. A review of all the passenger cars on the market may get a higher rating in our mid-priced sedans report than it gets in our economy cars report if the review covers mid-priced sedans more thoroughly. In other words, our ratings are not an indication of the article's credibility apart from the specific category on which we're reporting.

Why is the Calibration Chart printed on this paper? The colors on the Calibration Chart only appear as they should on matt art card. But the colors appear differently on other types of paper that I am printing on.

All Iron Oxide pigments are very chemical resistant. Only in very highly concentrated acids are these materials soluble. Mixed Metal Oxides and Chromium Oxide Greens are also very chemical resistant. The only materials that Hoover Color offers with limited chemical resistance are the Tuscan Reds and Orange and the Van Dyke and 925 Browns.

Chemical resistance is affected by a multitude of factors. Typical factors are the chemical (or a mixture with its major constituents), its concentration, the reaction temperature and duration, the pressure and additional factors such as stress conditions or the sliding stress. Guidance regarding room temperature information can be found in the list on chemical resistance in the ENSINGER brochure "Engineering Plastic Properties and Processing Guidelines".

Resistance is affected by a number of factors, namely concentration, heat and duration etc but generally the best options are usually, Polypropylene, HDPE, PVC and PTFE.

The chemical in the phase change material technology coolpacks is completely nontoxic, safe, and environmentally friendly. If swallowed, it acts as a laxative. Should the Cool Pack become punctured and bleed onto your skin, it may cause very minor irritation, so it's important that you scrub with soap and water. If you'd like a Material Safety Data Sheet on this product, just go back to our Technical Info page, and click on the MSDS page link.

MSDSs that represent non-hazardous chemicals are not covered by the HCS. Paragraph 29 CFR 1910.1200(g)(8) of the standard requires that "the employer shall maintain in the workplace copies of the required MSDSs for each hazardous chemical, and shall ensure that they are readily accessible during each work shift to employees when they are in their workarea(s)." OSHA does not require nor encourage employers to maintain MSDSs for non-hazardous chemicals.

Resistance is the unwillingness of a subject to accept the hypnotic process; usually due to an inhibition, fear of hypnosis or fear of another nature existing in the client. A school in my area is holding a weekend course and says I will be able to call myself a "Hypnotherapist" and know everything I need to open a professional practice. Is this true!

Since the primary ingredient in brick is clay which is fired to around 2000 F, it is a non-combustible material. As such, it is an excellent cladding choice to resist or confine fires. A brick wall's fire resistance rating can be calculated. This is done by extrapolating from known fire resistance periods for a given thickness of wall. Refer to Technical Notes 16B for further information on how to calculate fire resistance ratings for specific brick walls.

The new combined rollover resistance rating system predicts a vehicle's chance of rollover in single-vehicle crashes by: (1) an at-rest laboratory measurement known as the Static Stability Factor (SSF) which determines how top-heavy a vehicle is, and (2) the results of a dynamic maneuvering test that determines how susceptible the vehicle is to an on-road un-tripped rollover.

No, even a five-star vehicle has up to a 10 percent risk of rolling over in a single vehicle crash. In fact, because of the aggressive way in which the vehicle is driven and/or the age and skill of the driver, certain five-star vehicles such as sports cars, may have a higher number of rollovers per hundred registered vehicles than certain three-star vehicles, such as mini vans, due to the fact that they are in more single vehicle crashes.

The WELS Scheme replaces the voluntary National Water Conservation Rating and Labelling Scheme (the 'AAAAA' Scheme). The 'AAAAA' label may continue to be applied to new products until 1 July 2006, but will not be used after that date.
