Characteristics of TRYMER

Insulation Efficiency

The k-factor is a measure of thermal (heat) conductivity. At a given thickness, insulation with a lower k-factor reduces energy costs by providing more resistance to heat transfer. TRYMER brand insulation has a very low average k-factor for temperatures ranging from -297* to +300*F (-183* to +149*C)

The k-factor indicates the ability of a material to conduct heat. Lower k-factors indicate better thermal performance. At a specified k-factor, TRYMER brand insulation reduces installed system costs and allows you to use thinner cross sections.

This allows:

*Use of less insulation, sealant, vapor retarder and jacketing

*Insulated pipe can be installed in tighter spaces.

Light Weight

The weight of an insulation system impacts the static loading of the support structure, which could require costly design modifications. The weight of an insulation material is directly related to it’s k-factor and structural density.

How does TRYMER brand insulation rate? Consider service temperatures ranging from -30* to +250*F (-35* to 121*C) with the required insulation thickness. TRYMER brand insulation was the lightest, compared with other insulation materials, by up to 15.5 pounds per three-foot length.

Moisture Resistance

Water has a thermal conductivity 10 to 20 times greater than most insulation materials. As a consequence, when moisture penetrates an insulation, it raises the insulation’s thermal conductivity and lowers its long term effectiveness.

Water absorbed into the insulation not only reduces insulation efficiency, it also adds weight to the line, increases the likelihood of corrosion, and can contribute to fungal and bacterial growth.

In cold service, water can freeze, causing the eventual destruction of the insulation. In food and beverage plants, frequent wash downs with scalding water are cause for concern. For these reasons, resistance to water absorption is an important factor in the selection of insulation material.

Choosing a moisture-resistant insulation such as TRYMER helps ensure long-term insulation effectiveness in these types of services.

Low Moisture Vapor Permeability

It is important to recognize that an effective insulation system should not wick or transport water from a breach in the jacket to the pipe surface or along the pipe. In this sense, the insulation is a second line of defense for the pipe against the entry of water.

The accumulation of water within the insulation system often requires major maintenance and repairs. For these reasons, resistance to water absorption is an important factor in the selection of an insulation material for pipes and vessels. TRYMER brand insulation has a low moisture vapor permeability that can provide a temporary, second line of defense should the primary vapor retarder fail.


Compressive Strength

An insulation’s compressive strength provides support to the insulation system. Vapor retarders, sealants and jacketing all function better with a firm, rigid base. Also, a high compressive strength increases the static load that can be applied to the pipe and jacketing. It also permits hanger installation on the outside of the jacketing, eliminating direct routes for moisture and heat transfer. Choosing an insulation with the right compressive strength required for your application is vital to ensure long-term performance.

TRYMER brand insulation is available in grades that offer a compressive strength from 19 to 140 pounds per square inch.
