3. Noise Reduction Properly installed weather stripping minimizes wind noise and road sounds, providing a quieter ride. A damaged or worn-out seal can lead to an increase in cabin noise, detracting from the overall driving experience.

Drafts under doors are more than just an annoyance; they can have a profound impact on a home's heating and cooling efficiency. When cool air enters during winter months or warm air escapes in summer, HVAC systems must work harder to maintain the desired indoor temperature. This increased workload translates to higher energy bills and can shorten the lifespan of heating and cooling units. According to estimates, properly sealing gaps under doors can save homeowners between 10% to 20% on their energy bills annually. This is especially significant for those living in regions with extreme weather conditions.

3. Etherification Once the cellulose is sufficiently alkalized, controlled amounts of ethylene oxide are introduced. This step typically occurs under controlled temperature and pressure conditions to minimize side reactions and ensure a uniform product. The etherification process can be conducted in batch or continuous systems, depending on the desired scale of production.

5. Heat if Necessary In cases where complete dissolution is challenging at room temperature, gently heat the mixture to about 60-70°C (140-158°F). Heating helps dissolve the HPMC more effectively. However, it is crucial not to exceed this temperature as it may degrade the polymer.

3. Neutralization and Precipitation Following the etherification reaction, the reaction mixture is neutralized to halt further reactions, usually through the addition of an acid, such as hydrochloric acid. Once neutralized, the product is precipitated out of the solution, often by adding it to alcohol or another solvent that is less soluble in water. This step helps to purify the HEC and remove any unreacted reagents.
