The glass transition temperature is defined as the temperature range at which an amorphous material transitions from a brittle or glassy state to a more rubber-like, ductile state. This transition is crucial for understanding the thermal and mechanical properties of polymers. Below Tg, the molecular motion is limited, leading to a rigid and brittle structure. As the temperature increases past this threshold, the mobility of the polymer chains increases, resulting in enhanced ductility and flexibility.

At its core, HEC is produced by the etherification of cellulose with ethylene oxide. This chemical modification results in the introduction of hydroxyethyl groups (-CH2-CH2-OH) onto the cellulose backbone, significantly altering its solubility and functionality. The degree of substitution of hydroxyethyl groups can affect the properties of HEC, such as its viscosity, solubility, and thermal stability. HEC typically exhibits excellent water retention and forms a gel-like consistency when mixed with water, which is critical for many of its applications.

In the food industry, HPMC serves various roles due to its thickening, gelling, and stabilizing properties. It is used in products such as sauces, dressings, and dairy items to enhance texture and maintain the desired consistency. Additionally, HPMC is a commonly used substitute for fat in low-calorie food products, allowing manufacturers to create healthier alternatives without compromising quality. Its ability to retain moisture makes it ideal for baked goods, adding freshness and extending shelf life.

HPMC is available in different viscosity grades, which are determined primarily by the molecular weight and degree of substitution of the cellulose chain. These viscosity grades reflect how the polymer behaves when dissolved in water, measured in centipoise (cP), a unit for dynamic viscosity.
