Slip Resistance & Shock Absorption Explained

Slip, shock absorption and ball rebound are the 3 core sports-floor metrics that trade off against each other. Definitions, tests and per-scenario balance.

Interstellar — Anti-Slip grain-point R10 / +100% friction

Quick answer: A sports floor's 3 core metrics constrain each other: slip (friction), shock absorption (cushioning), ball rebound (sport feel). Maximizing one sacrifices the others: too much grip risks ankle strain; too much shock absorption lowers ball rebound; too much rebound = too hard. Balance by scenario: basketball needs rebound ≥95% + shock absorption 25-35%; kindergartens 50-70% + R10; senior care R10 + 50-70%.

Three Core Metrics

Slip: BPN (≥47 floor) or R-grade (DIN 51130, R10 for public)
Shock absorption: 25-35% basketball, 50-70% kindergarten, 70-80% high-fall
Ball rebound: ≥90% floor, ≥95% pro, ≥98% events (FIBA)

Per-Scenario Balance

Scenario	Balance	Pick
Basketball	Rebound ≥95% + absorption 25-35%	ANK5 / Quantum Stack
Kindergarten	Absorption 50-70% + R10	ANK4 / SVS1
Senior/wet areas	R10-R11 + absorption 30-50%	Interstellar
High-fall zones	Absorption 70-80% + thick	SVS1 thickened

Reading Performance Reports

Check test standard, conditions (23±2°C, 50±5%RH), result, and ≥5 test points averaged. Performance varies with thickness, so confirm the report matches your purchased thickness. See spec reading.

FAQ

Is higher shock absorption always better?

No — above 60% the floor gets too soft, ball rebound drops. Basketball's sweet spot is 25-35%.

Is higher slip always better?

No — BPN>130 risks ankle strain on stops/turns. BPN 60-90 is the comfort zone.

R10 vs R11?

R10 for general public spaces; R11 for wet-prone areas (kitchens, poolside).

BPN vs R-grade, which is stricter?

Different test conditions, no direct conversion. Quality products test both.

What is Anti-Slip grain-point tech?

AnchorCare's micro raised-point surface, ~500k points/㎡, +100% dry / +150% wet friction over flat PP.
