Optimal adhesion values are also obtained for overmolds onto PC (Lexan), ABS (Cycoloy), PC/ABS(Cycolac) and PC/PBT (Xenoy) as demonstrated in Figure 5. This good bonding performance was observed within a wide range of melt processing temperatures as shown in Figure.5. olycarbonate derived from Bisphenol A (PC) - Totally Amorphous P oly(acrylonitrile-co-butadiene-styrene) (ABS – 15%-35%AN,5-30%BD,40-60%ST) – Totally amorphous P C* Acetal Homopolymer – 98% crystalline Acetal Copolymer igure 4.

According to a McKinsey & Company report, modular projects: • have established a solid track record of accelerating project timelines by 20 to 50% • can deliver over 20% in construction cost savings when optimized for scale In a survey conducted by Prefab Modular Smart Market Report (2020): • 91% of contractors reported improved budget performance when using modular techniques • 68% of these indicated savings of 5% or higher • respondents indicated reductions in project durations of 20 to 50% Another factor—the well-publicized shortage of available and affordable housing stock—is also contributing to the rise of modular construction, particularly in urban areas with high demand and limited space. Many contractors report improved budget outcomes with modular techniques Modular methods shorten project timelines by 20–50% PROJECT TYPES Benefits of Modular Construction BUDGET PERFORMANCE COST REDUCTION Multifamily, commercial, and healthcare construction projects are increasingly using modular techniques Contractors see cost savings over 5% from modular construction PROJECT DURATION MARKET DYNAMICS Source: Avient Modular and off-site construction projects demand materials that do more: streamline projects without sacrificing performance.
